Question

Now consider what happens when a switch in the circuit is opened. Open Switch The figure shows a circuit consisting of the following elements connected in series: a battery, a group of two bulbs, labeled A and B connected in parallel, and a group of three bulbs, labeled C, D, and E, containing two branches connected in parallel. One branch has bulb C and another branch has a switch, which is open on the figure, and bulbs D and E connected in series Part B What happens to the brightness of bulb A?

Explanation / Answer

Answer) (PART B) it gets dimmer so it is option a . Bulbs A and B are connected in parallel so voltage is same through them but current flowing through the circuit changes since switch is open at bulbs D and E . So power reduces so bulb A gets dimmer .

(PART C) It gets brighter so it is option b since maximum supply is through bulb C so bulb gets more supply so it's brightness increases.
