14. Power supplies are regulated to prevent the output voltage from changing due to changes in the
- line voltage
- supply load
- frequency
- both line voltage and supply load
15. If current through a resistance is halved
- the resistance is halved
- the voltage is halved
- the voltage doubles
- none of the above
16. Ohm's law is a relationship between
- voltage, current, and time
- power, current, and resistance
- resistance, time, and current
- voltage, current, and resistance
