True or False: The current that leaves the source must make a complete circuit and return to the source.

True or False: The current that leaves the source must make a complete circuit and return to the source.

• A. True
• B. False
• C. Only in AC circuits
• D. Only in DC circuits

Answer: (A)

The statement is true because, in electrical circuits, for current to flow, it requires a closed path or a complete circuit. This means that electricity must travel from the source—like a battery or generator—along the conductors through the components of the circuit, such as resistors or appliances, and then return back to the source. This closed-loop configuration ensures that the electrical current can continuously move, thus enabling the operation of devices connected to the circuit. In both AC (Alternating Current) and DC (Direct Current) circuits, this principle holds true. For AC circuits, the current periodically changes direction, but it still needs a complete path for flow. Similarly, in DC circuits, the current flows in one direction and also requires a complete circuit to return to the starting point. Therefore, it’s essential for the current to complete the loop to maintain consistent flow and functionality in the circuit.
