The relation between power dissipation and resistance is given by
View all questions of this test
P = E2/R i.e Power dissipation is indirectly proportional to the resistance. Hence if the value of R is decreased, the power dissipation in the circuit will increase. Hence the assertion is correct. But the reason is incorrect as it mentions that the power dissipation is directly proportional to the resistance of the circuit which contradicts the relation between power dissipation and resistance of the circuit.

Directions: In the following questions, a statement of assertion (A) ...
Assertion: A resistor of resistance R is connected to an ideal battery. If the value of R is decreased, the power dissipated in the circuit will increase.
Reason: The power dissipated in the circuit will increase.
Explanation:
Assertion (A) is true but reason (R) is false.
When a resistor of resistance R is connected to an ideal battery, the power dissipated in the circuit can be calculated using the formula:
P = V^2 / R,
where P is the power dissipated, V is the voltage across the resistor, and R is the resistance.
If the value of R is decreased, the resistance of the circuit decreases. According to Ohm's Law (V = IR), when the resistance decreases, the current flowing through the circuit increases, assuming the voltage remains constant.
Key Point: Decrease in resistance leads to an increase in current.
Now, let's consider the power dissipation formula. If the resistance is decreased, the denominator of the formula decreases, which results in an increase in power dissipation. This can be seen by rearranging the formula:
P = V^2 / R,
If R decreases, the power P increases.
Key Point: Decrease in resistance leads to an increase in power dissipation.
Conclusion:
Therefore, the assertion is true because a decrease in resistance leads to an increase in power dissipation. However, the reason is false because it does not provide a correct explanation for the assertion. The reason implies that the power dissipated in the circuit will increase, which is correct, but it doesn't explain why the power increases when the resistance decreases.
Reason: The power dissipated in the circuit will increase.
Explanation:
Assertion (A) is true but reason (R) is false.
When a resistor of resistance R is connected to an ideal battery, the power dissipated in the circuit can be calculated using the formula:

If the value of R is decreased, the resistance of the circuit decreases. According to Ohm's Law (V = IR), when the resistance decreases, the current flowing through the circuit increases, assuming the voltage remains constant.

Conclusion:
Therefore, the assertion is true because a decrease in resistance leads to an increase in power dissipation. However, the reason is false because it does not provide a correct explanation for the assertion. The reason implies that the power dissipated in the circuit will increase, which is correct, but it doesn't explain why the power increases when the resistance decreases.
