Define RMS.
The value of AC voltage that will produce as much power when connected across a resistor as a like amount of DC voltage
Define Average Voltage
The value of DC voltage when it is rectified from AC voltage (Dependent on type of AC waveform)
How many degrees is 1 complete cycle of AC current
360°
In a RC parallel circuit. What is the relationship between current through resistor and current through capacitor
90° out of phase (capacitor leads)
When using a volt meter to get AC voltage. What voltage is being indicated?
RMS
In pure inductive circuit. What is the relationship between current and voltage?
Current lags by 90°
Why is AC better than DC?
