```ELE 100 Electrical Principles Quiz 2 (5 points)
April 20, 2005
Name ________________________
1. The voltage across a 100 ohm resistor is 12 volts. What is the current through the
resistor? Be sure to specify units of measure.
2. What is power and what is the standard unit of measure of power in the meterkilogram-second system?
3. If a dc motor is required to lift a constant load, how does the angular velocity of
the motor change as the applied voltage increases?
4. If a constant voltage is applied to the terminals of a dc motor, how does the
angular velocity of the motor change as the mechanical load on the motor
increases?
5. What power is required to lift a 300 gram mass at a velocity of 10 centimeters per
second?
