An automobile starter motor has an equivalent resistance of 0.0710 2 and is supplied by a 12.0-V battery with a 0.0320-2 internal resistance. (a) What is the current to the motor? 116.50 A (b) What voltage is applied to it? 8.2718 ✓ V (c) What power is supplied to the motor? 0.9636 kW (d) Repeat these calculations for when the battery connections are corroded and add 0.0900 2 to the circuit. (Significant problems are caused by even small amounts of unwanted resistand in low-voltage, high-current applications.) I= 12.3583 A V= P= 12.3958 x Check your calculations. V 153.1910 x Check your calculations. kW
