____ stops flowing in the circuit because there is no longer a complete loop?

• A. Current
• B. Voltage
• C. Charge
• D. Power

Answer: (A)

The flow of electric charges, called current, only exists when there is a complete path for charges to travel. If the loop is broken, the circuit becomes open, so charges can't move continuously from the source back to itself. With no closed path, current drops to zero even if a voltage source is present, because there’s nowhere for the charges to go. You can still have a voltage difference across the open gap, but that doesn’t drive a sustained flow. Power, which depends on current, also drops to zero when there’s no current flowing. Charges may briefly accumulate near the break, but there’s no continuous movement through the circuit.
