Homework Statement
You are tasked with designing an electrical circuit with a motor, a battery, and several 1ohm and 2ohm resistors. The motor is designed to run at a current of 20A and a voltage of 10V, but your battery supplies 15 V. The motor can then lift a 4kg mass 2.25 meters in 0.5seconds.
A.) Draw a circuit diagram of how to hook up the motor with resistors so that the motor gets the appropriate voltage.
B.) Determine the electrical input to the motor over the course of 100 seconds, both in Joules and kWh.
C.) Determine the power output of the motor lifting the mass.
D.) Determine the efficiency of the motor lifting the mass.
