Detailed Solution

The resistor value in the given circuit shown in the adjoining figure is

2 k Ω

.
Given data in the problem,
Current in the circuit,

I = 13 mA

Voltage across the circuit,

V = 26 V

By using the ohm’s law,

V = IR

, where

V

is voltage,

I

is the current, and

R

is resistance.
Putting the values in the above equation,

\Rightarrow 26 = 13 \times \frac{1}{1000} \times R

By rearranging the above equation,

\Rightarrow R = 2000 Ω

\Rightarrow R = 2 k Ω
