    A= Won’t light up as there is no battery.
    B= Won’t light up because the switch is open.
    C= Will light up because it has everything it needs.
    D= Will light up.
    E= Will light up
    F= Will not light up as it doesn’t have a switch.

      Well done Mario – good to see you on here. How are you doing with the other work?

  2. Zara H.

    A Will not light up because there is no battery.
    B Will not light since it is off.
    C Will light up because everything is where it needs to be.
    D Will light up because everything is correct
    E Will light up
    F Will not light up because it needs a switch.

  3. Riyad U.

    A will not light up because there is not and battery inside the circuit. Battery is necessary in a circuit as its the only object that produces energy.
    B will not light up because there is a switch that hasn’t been turned on. Without a switch that is not on, a circuit will not work because everything has been turned off.
    C will light up because the switch has been turned on.
    D will light up because as everything has been connected and there is no way to prevent the electricity from travelling.
    E will light up as there is a cell inside the circuit. The amount of lamps do not change the circuit.

  4. Christiana D.

    A will not light up as there is no battery (cell) in the circuit to make it work.
    B would not make the lamp light up because there is an open switch.
    C will light up
    D will light up
    E will light up
    F will not light up as it needs a switch.

      Well done, Luiza.
      Nice to see you on here.

      Keep working everyday!

    A will not light up as there is no battery (cell) in the circuit to make it work.
    B would not make the lamp light up because there is an open switch.
    C will light up
    D will light up
    E will light up
    F will not light up as it needs a switch.

      Good.

      What is the difference between a series and a parallel circuit?

  6. Safa H.

    A) A will not operate as there is no battery ( Cell ). A circuit must have a battery ( Cell ) in it in order to operate. Additionally, all of the energy is provided by the battery ( Cell ).

    B) B will not operate as the light switch is open. If the switch is open there will be a disparity in the circuit. This will result in, the circuit being incomplete.

    C) C will operate as the circuit is completed. Furthermore, all of the necessary things you need in a circuit are included. E.G:
    – Lamp
    – Battery
    – Closed switch

    D) D will light up as all of the necessary things are included in the circuit.

    E) E will light up and it doesn’t have switch. This means that it will work until taken apart as there is nothing that can open or close like a switch.

    F) F won’t light up as it needs a switch but doesn’t have one.

    1. Mr Patel

      Good answers. In modern circuits, does it always need a switch? What do you think?

      1. Safa H.

        No, this is because the purpose of a switch is to make it easier to open and close a circuit. The purpose of a circuit is to light up the lamp. You don’t need a switch to light up a light.

  7. Safa H.

    A) A will not operate as there is no battery ( Cell ). A circuit must have a battery ( Cell ) in it in order to operate. Additionally, all of the energy is provided by the battery ( Cell ).

    B) B will not operate as the light switch is open. If the switch is open there will be a disparity in the circuit.

    1. Mr Patel

      Good so far, Safa.

      How are you and your family?

      1. Safa H.

        We are good.

      2. Safa H.

        How are you?

  8. Amaan D.

    A. Cannot light up as there is no switch
    B. Can’t light up as there is a open switch which closes the circuit.
    C. Can light up
    D. Can light up
    E. Can light up
    F. Won’t light up as it needs a switch.

    1. Mr Patel

      It is nice to see you on the blog! I was wondering where you were?

      How is your family?

      Well done for doing this – keep this up.

      1. Amaan D.

        Thank you for the reply and my family is very good how is yours?

        1. Mr Patel

          All ok thanks but the isolation is crazy!

  9. Leona D.

    A- will not light up because there is no cell or battery and a battery is very useful because that’s where all of the energy comes from.
    B- will not light up because the switch is not on and even though there Is a battery the battery or cell will not create energy if the switch is off.
    C-will light up because everything is not just in place but everything is on e.g the switch which means that the battery or cell is on so it can create energy so that the lamp can turn on.
    D will light up because eventhough there is not a switch it just means that there isn’t a way to turn it off and on again.
    E will light up because there is a cell and a cell is able to create energy as there is a way for the energy to pass to the lamps and it doesn’t make a difference if there is 2 lamps because they both still join to the cell.

    1. Mr Patel

      This is a great, detailed response. Well done.

      Why are circuits important in your everyday life?

  10. Mahamad Y.

    A will not light up because there is no battery (cell).
    B will not light up because the switch is an open switch.
    C will light up as it has a closed switch, a cell and a lamp.
    D will light up.
    E will light up but it would last forever until taken apart because there is no switch to decide whether it stays open or stops the circuit.
    F will not light up.

    1. Mr Patel

      Hi Mahamad,
      How are you? Hope you are looking after your little brother? He seem cool!

      Good lad for completing.

      How have circuits changed in the past 20 years? Think about how smart devices have evolved.

      1. Mahamad Y.

        I am good thank you.

        Circuits and devices have changed and evolved in the past 20 years as the components of the circuit became smaller but more powerful and capable. The circuits now changed as most products now use Printed circuit Boards (PCB). Before there was point to point wiring. Older circuit boards had many different methods but they also had less restrictions then the modern day circuits.

  11. Mustafa G.

    A will not light up because there is no cell.
    B will not light up because the switch is not on.
    C will light up because everything is in its place.
    D will light up.
    E will light up.
    F won’t light up because it doesn’t have a switch.

    1. Mr Patel

      Good lad. How do circuits in a smartphone differ to a light switch?

      1. Ayub A.

        Part 1: Which of the circuits below will allow the lamp to light up?
        A)A does not light up because it doesnt have battery. It has 2 switch which is a full complete cirucit.

        Part 2: Explain why the circuits which won’t light up don’t work?
        Ciruit E will not light up as here needs be 2 batteries as there are 2 lamps.

  12. Humaira K.

    A.)Will not light up because you need the cell.
    B.)Will not light up because the switch is not activated and you need a cell but in the pic there is is’nt a cell.
    C.)Will light up.
    D.)Will light up.
    E.)Will light up.
    F.)It will not light up because it needs a switch.

    1. Mr Patel

      Good. What is the difference between a series and a parallel circuit?

      1. Humaira K.

        The difference is in a parallel circuit there is more than one loop however in a series circuit there is only one loop.

  13. Ayaan P.

    A will not light up because there is no cell for the energy to come from.
    B will not light up because the switch is not activated and there is no cell for the energy to come from.
    C will light up.
    D will light up.
    E will light up.
    F will not light up as it needs a switch,

    1. Mr Patel

      What circuits are used in your home? How have they changed in the past 30 years?
