What condition is required for electrical current to flow in a circuit?

Explanation:
Current flows only when there is a complete loop for charges to travel from the power source, through the conductors and load, and back to the source. If the circuit is open, there’s a break in the path, so charges can’t keep moving and no current flows, even if a voltage is present. The type of load doesn’t determine whether current can exist—what matters is having a closed path that provides a complete circuit for the current to travel.
