Question 10
Use two 1.5 V electric cells in holders, two LED lamps or 3 V lamps, electrical wires and two switches (a breadboard is optional). The cells are in series; each lamp has its own switch in a separate parallel branch, as shown.
From your results, predict what will happen if you add a third lamp in parallel with the two you already have in your circuit. What is the best way to test your prediction?
