Question

Study the following electric circuit and calculate the potential difference across 5 St resistor.
351 411 551
3V


CBSE Class X Science SA 2 (3 Marks)

Answer 1

V = IR

R=3 +4+5= 1211

3 = 1 x 12

3 1

I = 12 — =-4 = 0.25 Ampere.

Potential difference across 5 Sl resistor.

V = IR

V = -1x5 = Vor 1.25V
