Assertion: A lamp consumes 1000 J of electrical energy in 10 s. Its power is 100 W.
Reason: Power is obtained by dividing the energy consumed by the time taken.
Explanation:
Definition of Power: Power is the rate at which work is done or energy is transferred or converted.
Assertion (A) Explanation:
The assertion states that a lamp consumes 1000 J (joules) of electrical energy in 10 s (seconds). This means that the lamp has converted 1000 J of electrical energy into another form, such as light or heat, in 10 s.
Reason (R) Explanation:
The reason states that power is obtained by dividing the energy consumed by the time taken. Mathematically, power (P) is given by the equation:
P = E/t
Where P is power, E is energy, and t is time.
In this case, the energy consumed by the lamp is 1000 J and the time taken is 10 s. Therefore, the power of the lamp can be calculated as:
P = 1000 J / 10 s = 100 W (watts)
The reason correctly explains how to calculate power using the given energy and time values.
Conclusion:
Both the assertion and the reason are true, and the reason is the correct explanation of the assertion. The power of the lamp is indeed 100 W, which is obtained by dividing the energy consumed (1000 J) by the time taken (10 s). Therefore, the correct answer is option A.
Reason: Power is obtained by dividing the energy consumed by the time taken.

Definition of Power: Power is the rate at which work is done or energy is transferred or converted.

The assertion states that a lamp consumes 1000 J (joules) of electrical energy in 10 s (seconds). This means that the lamp has converted 1000 J of electrical energy into another form, such as light or heat, in 10 s.

The reason states that power is obtained by dividing the energy consumed by the time taken. Mathematically, power (P) is given by the equation:
P = E/t
Where P is power, E is energy, and t is time.
In this case, the energy consumed by the lamp is 1000 J and the time taken is 10 s. Therefore, the power of the lamp can be calculated as:
P = 1000 J / 10 s = 100 W (watts)
The reason correctly explains how to calculate power using the given energy and time values.
Conclusion:
Both the assertion and the reason are true, and the reason is the correct explanation of the assertion. The power of the lamp is indeed 100 W, which is obtained by dividing the energy consumed (1000 J) by the time taken (10 s). Therefore, the correct answer is option A.
