Question

6 - electronics information
a switch starts or stops the flow of electric current in a circuit by means of its
a probes.
b contacts.
c resistors.
d insulators.
if b is your answer, click the next button. otherwise, select another answer.

Explanation:

A switch uses contacts. When the contacts are closed (touching), current can flow. When they are open (not touching), current is stopped. Probes are for testing, resistors limit current, and insulators block current flow (not for starting/stopping in a switch's function).

Answer:

B. contacts
