An automobile starter motor has an equivalent resistance of, Ask an Expert

Academics

An automobile starter motor has an equivalent resistance of 0.0480 and is supplied by a 12.0 V battery with a 0.0080 internal resistance.

(a) What is the current to the motor?

(b) What voltage is applied to it?

(d) Repeat these calculations for when the battery connections are corroded and add 0.0900 to the circuit. (Significant problems are caused by even small amounts of unwanted resistance in low-voltage, high-current applications.)
