Final answer:
A half-duplex circuit allows two-way communications but in one direction at a time, contrasting with full-duplex circuits. It is commonly used in devices like walkie-talkies.
Explanation:
Half-Duplex Circuit is the type of circuit that provides two-way communications but in only one direction at a time. An example of this is a walkie-talkie where one party talks while the other listens, and then they switch roles.
A half-duplex circuit allows communication in both directions but not simultaneously, unlike a full-duplex circuit where communication can occur in both directions simultaneously.
Understanding circuit configurations like half-duplex circuits is essential in the study of electrical engineering and communication systems.
