a switch starts or stops the flow of electric current in a circuit by means of its\na probes.\nb contacts.\nc resistors.\nd insulators.
Answer
Brief Explanations:
A switch has contacts that can be opened or closed. When the contacts are closed, the circuit is complete and current can flow. When the contacts are open, the circuit is broken and current stops flowing. Probes are for testing, resistors limit current flow, and insulators prevent current flow.
Answer:
B. contacts.
