Solution

A current of 200 mA flows through a 4 kΩ resistor.
So current, I = 200 mA = 200 x 10-3A
Resistance, R = 4 kΩ = 4000 Ω
Potential difference, V = IR
V = 200 x 10-3 x 4000
V = 800 V
So the potential difference across the resistor will be 800 V.A current of 200 mA flows through a 4 kΩ resistors will be  800V

  Is there an error in this question or solution?
