Answer:
<h3>The power of headlight in series connection is 29.64 W</h3>Explanation:
Given :
Power of headlight W
Power of starter W
Voltage of headlight and starter V
From equation of power,
For finding the resistance of headlight and starter,
⇒ For headlight,
Ω
⇒ For starter,
Ω
Since equivalent resistance,
Ω
So power in series is given by,
W
