Question

A current of 200 mA flows through a 4 KΩ resistor. What is the p.d. across the resistor?

Answer 1

Answer:

Explanation:

Given'

Current(I) = 200 mA or 200 × 10^-3

Resistance(r) = 4k ohms or 4 × 10^3

Potential difference =?

We know,

Ohm's law:

V = IR

V = 200 × 10^-3 × 4 × 10^3

V = 800 volts

Hence potential difference across the resistor = 800 volts
