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.
current flows back and forth APEX
Current filtering
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
An "Alternating Current" (AC).
The sharing of current between different components in an AC circuit
because of the reactances in the circuit
