Question

An electric heater coil is connected to a 220V source. If the resistance of the heater coil is 220Ω, find the current.

Answer 1

Solution.

V= 220v
R=220ohm
find, I=?

so, V = IR

Therefore, I = V/R
I = 220/220
I = 1 A.

Answer 2

Answer:

Given:V=220volt , R=220ohm

Find:I=?

*By ohm's law*

V=IR

Therefore , I=V/R

I=220/220

"I=1A". ANSWER
