Question

1. after cranking the engine, the battery positive cable feels excessively warm. which of these could be the cause?

ca. an overcharged battery
cb. open stator ground
cc. high cable resistance
cd. overfilled battery acid

Explanation:

Step1: Analyze each option

• Option A: An overcharged battery would cause excessive current flow through the positive cable, generating heat due to \(P = I^{2}R\) (where \(P\) is power, \(I\) is current, and \(R\) is resistance).
• Option B: An open alternator ground would disrupt the charging circuit and not directly cause the positive cable to overheat.
• Option C: High cable resistance would cause voltage drop but not the kind of overheating described here.
• Option D: An overfilled battery would not cause the positive cable to overheat.

Answer:

A. An overcharged battery
