Question

The potential difference across the 3-ohm resistance in the following diagram is:​

Answer 1

Explanation:

R1 = 4OHM

R2= 3OHM

R3= 6OHM

1/R4 = 1/R2 +1/R3

= 1/3 + 1/6

= 1/2

R4 = 2

R5 = R1 + R4 = 4+2 =6 OHM

V=IR

3 = I×6

I = 1/2

POTENTIAL DIFFERENCE across the 3 ohm resistance is = IR = 1/4×3 = 3/4
