Question

If a power of 100 watt is being supplied across a potential difference of 200 volt current flowing is

Answer 1

Power = Potential difference X Current

I = P/V

I = 100/200

I = 0.5 A

Answer 2

Given that,

Power, P = 100 W

Potential difference, V = 200 V

To find,

Current flowing in the circuit.

Solution,

The electric power of an electrical appliance in terms of voltage and current is given by the formula as follows :

$P=VI$

I is electric current flowing in circuit

$I=\dfrac{P}{V}\\\\I=\dfrac{100\ W}{200\ V}\\\\I=0.5\ A$

So, the electric current in the circuit is 05 A.
