The headlights, radio, and defroster fan in an automobile are connected in
a. series with a switch for each.
b. parallel with a switch for each.
c. series without separate switches.
d. parallel without separate switches.
any help would be appreciated - thank you!
A series circuit requires ALL switches to be connected and all three devices would operate at the same time or not at all. With parallel connections, each can have its separate switch and be operated independently of the other devices.
