An electric lamp is connected to a 240 V DC source. The current flowing through the lamp is 0.25 A. The power of the lamp is:

Correct option is A

Correct Answer: A 60 W

Explanation:
The power of an electrical device can be calculated using the formula:

P=V×I

Where:

• P is the power in watts (W)
• V is the voltage in volts (V)
• I is the current in amperes (A)

Given:

• V=240 V
• I=0.25 A

Substitute the values into the formula:

P=240×0.25=60 W

Thus, the power of the lamp is 60 W.

Information Booster:

·         Power in an electrical device measures the rate at which energy is consumed or converted.

·         In a DC circuit, power is simply the product of voltage and current.

·         A 60 W lamp consumes 60 joules of energy per second.

·         The efficiency of a lamp depends on how much of this power is converted to useful light versus heat.

·         Power ratings help determine the suitability of electrical components for specific applications.
