22. An automobile starter motor has an equivalent resistance of 0.0500 and is supplied by a 12.0-V battery with a 0.0100-2 internal resistance . (a ) What is the current to the motor ? (b ) What voltage is applied to it? (c) What power is supplied to the motor ? (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 .)
