Detailed Solution

When an electric oven of

2 kW

power rating is operated in a

200 V

electric circuit with a current rating of

5 A

, then the current flowing in the circuit is

10 A

.
It is given that the Power

P = 2 kW

= 2000 W

Voltage

V = 200 V

We know that

P = VI

\Rightarrow I = \frac{P}{V}

Where

P

is power,

I

is current and

V

is voltage.
On substituting the given values, we get

I = 2000 / 200

\Rightarrow I = 10 A

Hence the current rating of the circuit is

5 A

, and the current flowing is

10 A

.
