Question

what is the power of a parallel circuit with a resistance of 1000 ohms restistance and a current of 0.03 a

Answer 1

The power P is found from the formula:

`P=I^(2)R`

`P=(0.03)^(2)*1000=0.9\ watt\ or\ 900mW`

Answer 2

0.9 Watts is the power of a parallel circuit.

Explanation:

Power is the product of square of current into resistance offered and its unit is Watt. Mathematically written as:

`P=I^2* R`

Where :

P = Power circuit

I = current in the circuit

R = resistance offered by the circuit

We have :

P = ? , I = 0.03 A, R = 1000Ω

`P=(0.03 A)^2* 1000 \omega =0.9 Watt`

0.9 Watts is the power of a parallel circuit.
