P=VI=I^2*R.

Resistance produces Heat.
Heat is a change in temperature.

Power rating they refer to a true power which is normally in the volt-Amp unit such as VA, KVA, MVA. So my answer is False.

Take a heater coil when we use its full length and when we use a fraction of it, power rating does change.

Basically, the formula for power is P = VIpf m also P = i * i * R, so it is related. but the answer says it is not maybe power rating they refer to a true power which is normally in the volt-Amp unit such as VA, KVA, MVA.

@Kundan.

My view is "Power is related to both current and resistance in the closed circuit".

p = i*i*R.

R-Resistance, so it will including in power value.
