The power P is found from the formula:
[tex]P=I^{2}R[/tex]
[tex]P=(0.03)^{2}\times1000=0.9\ watt\ or\ 900mW[/tex]

Answer:

0.9 Watts is the power of a parallel circuit.

Step-by-step explanation:

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

[tex]P=I^2\times R[/tex]

Where :

P = Power circuit

I = current in the circuit

R = resistance offered  by the circuit

We have :

P = ? , I = 0.03 A, R = 1000Ω

[tex]P=(0.03 A)^2\times 1000 \omega =0.9 Watt[/tex]

0.9 Watts is the power of a parallel circuit.
