Question

how much current will an electric heater draw of resistance 45ohm it is connected to 220volt line ​

Answer 1

Explanation:

We have given;

resistence or R= 45ohm

potential difference or V = 220V

Now, according to ohm's law;

V =IR;

Now, put the given values in thier respective variables;

220V = I * (45ohm)

I = 220 / 45;

I = 44 /9 ampere or 4.86 ampere

The amount of current drawn by electric heater from thw line will be 44/9 A or 4.86 A.

That's all.
