The automobile battery consists of an emf of 126 v and an, Ask an Expert

Academics

The automobile battery consists of an emf of 12.6 V and an internal resistance of 0.0800. The headlights altogether present equivalent resistance 4.80 (supposed constant).

(i) Determine the potential difference across the headlight bulbs if they are the only load on the battery?

(ii) Determine the potential difference across the headlight bulbs if the starter motor is operated, taking an extra 35.0 A from the battery?
