Question

If a current of 5 mA passes through a resistance of 2200 Ω, find out the voltage drop on it.

Answer 1

Answer:

According to the ohms law, if temperature is same then potential drop across resistor will be directly proportional to the current passing through it.

V=IR

Where

V= potential difference across the resistor

I= Current passing through resistor

R= proportionality constant also known as resistance.

So according to given data

Potential across terminal of 15 ohms resistor having current 5 ampere is

V=5*15=45Volts
