15 thoughts on “Year 4- What is wrong with the circuit?

  1. A)The wire is not connected to the battery so the
    electrons can not flow through.
    B)The wire is not connected to the buzzer so the
    electrons can not flow.
    C)Ther is no battery source for the electrons to come
    from.

  2. A) The electrons go to get charged but they don’t light the bulb because the charged electrons have no way of traveling to the light bulb to light it.
    B) The (charged)electrons don’t have a way to go to the buzzer to make it sound.
    C) There is no battery therefor there are no electrons to light the bulb.

  3. A The bulb will not go on because the second wire is supposed to be connected to the other side of the cell then the bulb will get charged.
    B The motor will not get on because the first wire is not connected to the space where the second wire is.
    C The bulb will not get on because there is no cell to make the electrons charge.

  4. A The wire isn’t connected to cell so the electrons won’t flow through and light the bulb.
    B The circuit isn’t fully complete because the first wire isn’t in the correct place.
    C Without the battery the electrons won’t travel to the bulb.

  5. A The second wire needs to be connected to the positive side of the battery
    B The second wire is not connected to the positive side of the battery so the electrons can’t come back to get electricity.

  6. A)The wires aren’t connected to both sides of the battery so it can’t recharge.Also not on both sides of the bulb so it won’t work.
    B)The wires aren’t connected to the buzzer and not on both sides of the battery.
    C)There is no battery for the bulb to work, so there’s no electricity.

  7. A) There is not a wire to connect to the light bulb and cell so the electrons won’t get charged again so the light bulb won’t work.
    B) The wire is not connected to the motor so the electrons can not flow through.
    C) There is no cell so their is no electrons to light up the bulb.

  8. Electricity

    A doen’ t work because the second wire needs to be connected to the other side of the battery to generate power to the bulb.

    B) B does not work because because the second wires positioning is incorrect the wire needs to be connected to the other side of the battery to make the th motterThen the electrons will generate power to the bulb.

    C) C doesn’t work because both wires are connected to the same terminal. Also the battery is missing.

  9. 1) the wire is not connected so it has ent finished the circet.

    2) This one doesn’t work because there is only one wire and no battery.

    3)there is no battery so the bulb won’t light

  10. A) This circuit will not light up because not all wires are connected so the power can not travel through the wire.
    B) This will not work as both the wires which are connected to the motor are connected to the same battery.
    C) There is no battery to provide power

  11. A)The bulb doesn’t light up because there is not another wire on the other side of the bulb bad battery.
    B)This bulb does not work because there are two wires on the same side which does not allow the bulb to light up.
    C)There is not any battery connected to the circuit or motors and also any electrics.

  12. A.It is wrong because it is not going from negative to positive terminal.
    B.The second circuit is also not right because the wire is not connected to the bulb properly.
    C.The third one is not working because there is no battery and if there is no battery,how will the bulb light up?

  13. A is wrong because the negative side don’t travel through the wire through the light bulb then travels to the positive side of the battery.

    B’s circuit is not complete because there’s no wire connected all the way round.

    C is wrong because there is no battery in the circuit and that means that there is no power in the circuit.

  14. A The wire is not connected to the battery so the electrons can not flow through.
    B the wire is not connected to the buzzer so the electrons can not flow through
    C There is no battery source for the electrons to come from.
