Final answer:
The statement is false; a transistor requires a base voltage to enable current flow between the source and drain, as the base acts as a controlling valve.
Step-by-step explanation:
The statement is False. Current typically cannot flow between the source and drain of a transistor when there is no potential, or base voltage, applied to the gate (or base) of the transistor. A junction transistor, which consists of an emitter, a base, and a collector, requires a base voltage to allow current flow from the emitter to the collector. The base acts as a valve, and the base current controls the larger collector current. Without this controlling voltage, the transistor remains off, and the current does not flow between the source and drain in normal operation.
