Two bulbs when connected in parallel to a source take 60W each, the power consumed, when they are connected in series with the same source is
Options
(a) 15W
(b) 30W
(c) 60W
(d) 120W
Correct Answer:
30W
Explanation:
In series, P = P₁P₂ / P₁+P₂
Given: P₁ = P₂ = 60
Therefore, Power P = (60 × 60) / (60 × 60) = 30 W.
