R1 = 2.15 0; R2 = 4.30 (2-, R3 = 10.75 9.; R4 = 6.45 n How much current ows through each of the four resistors? V R: R3 R4 5. [16 Points] SERPSEWA10 27.WA.006. An automobile starter motor has an equivalent resistance of 0.0460 9. and is supplied by a 12.0V battery with in 0.026041 internal resistance. (a) What is the current to the motor? A H (b) What voltage is applied to it? V H (c) What power is supplied to the motor? kW H (d) Repeat these calculations for when the battery connections are corroded and add 0.0900 0 to the circuit. (Significant problems are caused by even small amounts of unwanted resistance in lowvoltage, highcurrent applications.) 6.
