Question
1. A power company supplies a home with alternating current (ACcurrent). In AC current, electrons:A. move from the power company to the home.
B. move from the home to the power company.
C. move from the home to the power company and back.
D. move back and forth in a very small space.
2. A resistor is connected to an AC power supply. On this circuit,the voltage
A. lags the current by 90 degrees
B. leads the current by 90 degrees
C. is in phase with the current.
D. lags the current by 45 degrees
3. If you triple the rms in an AC circuit, what happens to themaximum voltage?
A. it increases by a factor of 3
B. It decreases by a factor of 3
C. It increases by a factor of 3
D. It decreases by a factor of 3.
Explanation / Answer
a)A power company supplies a home with alternating current (ACcurrent). In AC current, electrons move from the home to the powercompany. Since the direction of the eletron path is opposite to thedirection of the current. b)A resistor is connected to an AC power supply. On thiscircuit, the voltage is in phase with the current. c)You triple the rms in an AC circuit, then maximumvoltage increases by a factor of 3.Related Questions
