Switching Circuits Quiz

What is the primary function of a double-pole switch?

• To act as a fuse

• To connect multiple circuits

• To cut off current in both live conductors simultaneously

• To control a single live conductor

What does an ohmmeter indicate if there is no connection between the terminals?

• Zero ohms

• Infinite ohms or OL

• A small resistance value

• A fluctuating resistance

Which type of switch is used to control three conductors simultaneously?

• Single pole switch

• Double pole switch
