Question

Choose the correct statement:

When the same current $\left(i\right)$ flows through two circuits as shown in the figures, then (assume that all bulbs are identical)

(A) bulbs in the first combination glow with more brightness.

(B) bulbs in the second combination glow with more brightness.

(C) bulbs in both the combination glow with equal brightness.

• A. Only (A) is true
• B. Only (B) is true
• C. Only (C) is true
• D. Cannot be determined

Answer 1

The correct option is A

Only (A) is true

1. In a series circuit, the same amount of current flows through the bulbs.
2. In a parallel circuit, different amount of current flows through bulbs.
3. Bulbs in the first combination glow with more brightness as they are connected in series.
4. Bulbs in the second combination glow with less brightness as they are connected parallel.
5. Bulbs in both combinations do not glow with equal brightness because the brightness of the bulb in the first combination is more bright than the second combination.

Hence, bulbs in the first combination glow with more brightness.

Option (A) is the correct option.
