Question

What is the potential difference across the 3 ohm resistor ..?

Answer 1

Answer:

V=I R

Explanation:

1st we will find current

Req = 1+2+3=6 ohm

2=I ×6

I = 1/3

now,

V = 1/3 × 3

therefore,

V = 1

Current in the circuit = 2/6

= 1/3A

Potential drop across 2 ohm resistnace =

$\frac{1}{3} \times 2$

$\frac{2}{3} v$

Potential drop across 3 ohm resistnace=

$\frac{1}{3} \times 3$

$1v$

Potential across 3 ohm resistnace =

$1 - \frac{2}{3}$

$\frac{1}{3} v$
