Question

A current of 200 milli ampere flows through a 4k ohm resistor what is the potential difference across the resistor

Answer 1

i hope it will help you!!!

Answer 2

Hey there!

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
