Question

Consider the circuit shown in Fig.. The terminal voltage
of the 24.0 V battery is 21.2 V. What are (a) the internal resistance r
of the battery and (b) the resistance R of the circuit resistor?

0.5 N 5.0 V
2.0 N

Expert Solution

Step 1

Given , Emf of Battery = 24 V

Terminal voltage = 21.2 V

Voltage drop = 24 - 21.2V=2.80 V

$∆ V = i r = 2.80 V A n d i R = V - ∆ V = 21.2 V \frac{r}{R} = \frac{2.80}{21.2} = 0.1320$
