Electronic Circuit By Aisyah, Abigail and Vivek

How it works:

The electricity from the dry cell battery flows through the wires to all the three different bulbs through the 3 paths (3 different arrows - black red green)

When two of the bulbs are lit up, the brightness will be the same as it is a parallel circuit.

When three three bulbs light up all of the will be the same but will be dimmer than if it was only 2 bulbs or one bulb light up.

If it is in a series circuit one bulb is dependent on the other however in a parallel circuit it is no dependent which is more suitable for this activity.


  1. I like the idea of using different colours to differentiate the current flow.

  2. Good attempt. I would like your group to keep this few questions in mind when you are doing your activities 1.2 to 1.4.

    1) Should we draw the current flow when the circuit is open?
    2) When 3 bulbs are parallel, will they be dimmer as compared to 2 bulbs are parallel?
    3) Is the amount of current through the battery and hence circuit the same for two bulbs in parallel as compared to three bulbs in parallel?
    4) Is parallel circuit always independent?
