Question

An electric oven of 2kw power rating is operated in a domestic electric circuit (220v)that has a current rating of 5A. What result do you expect? Explain

Answer 1

Answer:

Not safe

Explanation:

Given:

• Power rating of the electric oven = 2 kw = 2000 watts
• Voltage at which the electric oven is operated = 220v
• Current rating of the electric oven = 5A

To find:

• What will happen

P=V×I

P=power

V=voltage

I=current

I=2000/220

I=9.09 Amperes

The current flowing here is more than the current rating which is 5 Amperes so its not safe and the fuse will start melting and circuit will get opened
