- One electric bulb is attached to a 220 V generator (current = 0.50A). Find the power of the bulb.
Electric power can be expressed as the rate at which work is done or energy is transmitted in an electric circuit. A given value of power can be generated by a value combination of current and voltage. In order to determine power of the bulb, we have to:
Step 1: Data Given
The following data is already mentioned:
- Voltage, V = 220 V
- Current, I = 0.05 A
Step 2: Finding Solution
Since the voltage and current of a bulb are already mentioned, power can be estimated via the derived formula of Power, which is:
Power = Voltage × Current
Thus,
⇒ p = 220 x 0.05p
= 22 x 0.5p
= 11 W
Therefore, the power which is required equals 11 W.
