Question

If a small appliance is rated at a current of 10 amps and a voltage of 120 volts,
what is the power rating?

Answer 1

Answer:

P=1200watts

Explanation:

Power=voltage*current

V=120v

I=10A

P=120v*10A

P=1200watts

Answer 2

The correct option about power rating is, “1200 V”.

What is Power?

The quantity of energy moved or transformed per unit of time is known as power, and its unit is "watt".

What are the different formulas for power?

• Power = Potential Difference × Current
• Power = ( Current )² × Resistance
• Power = ( Potential Difference )² / Resistance

How to solve this question?

We have given Potential Difference and current

So, we can use the formula which contain Potential Difference and current.

Which is,

Power = Potential Difference × Current

Power = 120 × 10 watts

Power = 1200 watts

Hence the power rating came out to be 1200 watt after solving.
