Question

When the power consumed by a bulb will be equal to the power rating

Answer 1

Answer:

If there is no resistance in the circuit and the potential difference across the bulb is equal to the voltage rating.

Explanation:

Answer 2

Power consumed by the bulb can be equated to power rating by following steps.

1. Removing resistance from circuit. So that whole voltage is transferred to the bulb so that bulb operates with maximum power.

2. A power rating is a measurement of the maximum amount of power that can be used with a specific tool or device. ... The power rating on these devices is usually determined by the amount of heat created from electrical power, as the heat that is created will damage the device if it reaches a certain level.
