Question

A heater of resistance 30 ohm is connected to 220-volt line. How much current will this heater draw

Answer 1

Current is 7.33 Ampere.

Hope it helps!!

Thank you ✌️

Answer 2

Answer:

7.33 ampere

Explanation:

Resistance = 30 ohm

Voltage = 220 volts

According to Ohm's Law,

Voltage = Current×Resistance

V = IR

220 = 30I

I = 7.33 ampere

Hence the heater will draw a current of 7.33 ampere.
