NEET Physics Question - Current Electricity - Power of Electrical Circuit

Assertion (A): In series combination of electrical bulb, lower power bulb emits more light than that of higher power bulb.

Reason (R): The lower power bulb in series gets more current than the higher power bulb.

(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)

(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(3) (A) is true but (R) is false

(4) Both (A) and (R) are false

Solution:

In a series circuit, the current \( I \) is the same for all components. The power dissipated by a bulb is given by \( P = I^2 R \). A lower power bulb has a higher resistance \( (R = V^2/P) \). Thus, it dissipates more power and glows brighter in series. Reason (R) is false because the current is the same for all bulbs in series.
