Question

Consider a circuit consisting of a battery and two bulbs. Explain why the following two
statements are direct consequences of the preceding definitions.
A. When two bulbs are connected in series, the same current that passes through one
bulb must also pass through the other.
B. When two bulbs are connected in parallel, current that passes through one bulb does
not pass through the other.

Expert Solution

Step 1

Defined terms:

The potential difference in the circuit is V
The current is I
The resistance is R
The power is P

Statement A:

No, the given statement is wrong. when two bulbs are connected in series then due to the different potential difference in the bulbs the current is different.

From the following mathematical expression, we can clearly understand it:

$I = \frac{V}{R}$ , here when V changes, I will change
