Question

10 ohm and 20 ohm resistors are connected in series with 3V cell. Find the current flowing through the 10 ohm resistor. potential difference across 20 ohm resistor

Answer 1

Current flowing through 10 ohm resistor is = V = I* R
I = R / V
I = 10 / 3
I = 3.33 A approx.

V = I*R
= 3.33 * 20
= 66.6 V
