The current in any AC circuit reverses every cycle.
For calculations Peak or magnitude is used.
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
leading the voltage.
The flow of electric current in an AC circuit is alternating, it flows one way then the other, with reference to ground.
The phase difference between the current through the resistor and inductor in an AC circuit is 90 degrees.
current flows back and forth APEX
Current filtering
An "Alternating Current" (AC).
The sharing of current between different components in an AC circuit
because of the reactances in the circuit
The average value of the alternating current (AC) in the circuit is calculated by finding the root mean square (RMS) value of the current waveform. This value represents the equivalent direct current that would produce the same amount of power dissipation in a resistor as the AC current.
