Question

What is meant by an electric iron rated 500watt?

Answer 1

Answer:

Explanation: it means that it will consume electricity at the rate of 500 joules per second

Answer 2

Explanation:

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
