Question

In the circuit shown below
Ώ
The potential difference across the 3 Ω resistor is
(a) 19 V
(b) 12 V
(c) 1 V
(d) 2 V; In the circuit shown below
Ώ
The potential difference across the 3 Ω resistor is
(a) 19 V
(b) 12 V
(c) 1 V
(d) 2 V

Answer 1

The potential difference across the 3 Ω resistor is 1 V.

Explanation:

The three resistors are connected in series with a battery of 2V.

R = R1 + R2 + R3 = 1 + 2 + 3 = 6 ohm.

So, the current flowing in each resistor is the same.

Therefore, $I=\frac{V}{R}=\frac{2}{6}=\frac{1}{3} A$.

Now, the potential difference across 3 Ω (R3) resistor,

$v=I \times R 3=\frac{1}{3} A \times 3 \text { ohm }=1 V$

Hence, the potential difference across the 3 ohm resistor is 1 V.
