Question

A battery of e.m.f. 24 V and internal resistance 4 is connected to a resistor of resistance 32 . Calculate the terminal potential difference of the circuit.

Answer 1

Answer:

21.33 volt

Explanation:

E = 24 emf

R = 32

r = 4

I = ?

V = ?

I = E/r+R

I = 24 / 4 + 32

I = 2 / 3 Amp

V = E - I×r

V = 24 - 2/3 × 4

V = 21.33 volts
