Question

the power rating of an electric iron is 500 Watt and 220 volt .find the resistance of the iron and the current drawn by the iron

Answer 1

Hey there !

Power = Volt * Current

Given that, Power is 500 W and Voltage is 220 V.

So Current can be found to be:

Current = Power / Voltage

=> Current = 500 / 220 = 2.27 Amperes.

Now, the resistance can be found out by substituting the values of Current and Voltage in Ohm's Law.

Ohm's Law = Voltage / Current = Resistance

=> R = 220 / 2.27

=> R = 96.9 ohms

This is the required answer.

Hope my answer helped !
