Which statement about direct current (d.c.) and alternating current (a.c.) is correct?
In a d.c. series circuit, the current decreases as it flows through each resistor.
In an a.c. circuit, the electric charge carriers drift continuously in one direction around the circuit.
In a d.c. circuit, the net flow of charge carriers is in one direction.
In an a.c. circuit, the magnitude of the current is constant over time.
