Assertion (A): In parallel combination of electrical appliances, total power consumption is equal to the sum of the power of individual appliances.

Reason (R): In parallel combination, the voltage across each appliance is the same.

1. both A and R are true and R is the correct explanation of A
2. both A and R are true and R is not the correct explanation of A
3. assertion is false but reason is true
4. assertion is true but reason is false

both A and R are true and R is the correct explanation of A

Explanation

Assertion (A) is true because in a parallel combination, each appliance operates independently and draws its own current. The total current supplied by the source is the sum of currents in all branches. Since total power is given by P = VI, the total power consumed becomes the sum of the individual powers of all appliances.

Reason (R) is true because in a parallel circuit, each appliance is connected directly across the source, so the same potential difference (voltage) is applied across each appliance.

Hence, both A and R are true and R is the correct explanation of A.
