Question

cell of EMF 2 volt with internal resistance 2 ohm and the external resistance at home from a closed circuit find the potential difference between the two ends of the external resistance​

Answer 1

Hello Dear,

# Correct question -

Q. Cell of EMF 2 volt with internal resistance 2 ohm and the external resistance 8 ohm form a closed circuit. Find the potential difference between the two ends of the external resistance.

◆ Answer -

V = 1.6 V

◆ Explaination -

Current flowing through circuit is -

I = E / (R + r)

I = 2 / (8 + 2)

I = 0.2 A

Voltage across external resistance is -

V = I.R

V = 0.2 × 8

V = 1.6 V

Hence, voltage across external resistance will be 1.6 V.

Thanks dear...
