Terms in this set (502)
AC sine wave AC power systems, both voltage and current continuously alternate
between maximum positive and negative values. This can be represented as
a sine wave.
Square root of three Always used when preforming three phase calculations
Amplitude A time period on which the value or current cycles from zero to max
positive to max negative and back to zero.

Electron flow Current equals flow. Voltage Equals pressure.
Generation of AC voltage and current Voltage is induced in a conductor as it passes through lines of force in a
magnetic field. Induced voltage causes a current to flow.
Root mean square Is the square root of the mean of squares of the instantaneous values of
current or voltage.
Peak to peak value The magnitude of the voltage or current measured between max positive
and max negative.
Purely resistive circuit AC voltage causes an AC current to flow through the resistance. Voltage
and current are said to be in phase.
Purely inductive circuit In this circuit, the current lags the applied voltage but 90 electrical degrees,
net power equals zero. No work can be performed.

Purely capacitive circuit In this circuit, the current leads the applied voltage by 90 electrical degrees,
net power equals zero so no work can be performed.
True power equation
Inductive reactance
