Problem 23PE

 Problem 23PE

An automobile starter motor has an equivalent resistance of 0.0500 Ω and is supplied by a 12.0-V battery with a 0.0100-Ω 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 Ω to the circuit. (Significant problems are caused by even small amounts of unwanted resistance in low-voltage, high-current applications.)

Step-by-Step Solution:
Step 1 of 3

Solution 23PE

  1.  the magnitude of the current flowing through motor is 200 A
  2. the magnitude of the applied voltage is 10.0V
  3.  the magnitude of the power supplied to the motor is 200kW
  4. Hence, the voltage applied 4.0 V and applied current is 80.0 A and power supplied is 320 W
