Final answer:
Plugs close female and caps close male is a true statement in electrical engineering.
Step-by-step explanation:
This statement is true. In electrical engineering, plugs and caps are used to connect or disconnect circuits. Plugs generally have pins or prongs that fit into the openings in an electrical socket, while caps have holes that fit onto the pins or prongs. In most cases, plugs are designed with a male connection and caps with a female connection. When a plug is inserted into a cap, the connections close and complete the electrical circuit.
