A passenger jeepney is running slowly and the mechanic and automotive electrician must decide whether to replace the dynamo, the high-tension cables, or the battery. It is a common knowledge to all automotive electricians that the 12-V battery should have no more than 0.020-Ω internal resistance, the dynamo not exceeding than 0.200-Ω resistance, and the high-tension cables not greater than 0.040-Ω resistance. The mechanic starts the jeepney and measure 11.4 V across the battery, 3.0 V across the cables, and a current of 50 A. Which part is defective
