A 250V bulb passes a current of 0.3A. Calculate the power in the lamp....
Given:
- Voltage (V) = 250V
- Current (I) = 0.3A

To find:
- Power (P) in the lamp

Formula:
- Power (P) = Voltage (V) x Current (I)

Calculation:
Substitute the given values into the formula to find the power.

P = 250V x 0.3A
P = 75W

Hence, the power in the lamp is 75W. Therefore, the correct answer is option 'A'.
