E6F08 : Why are optoisolators often used in conjunction with solid-state circuits that control 120 VAC circuits?
A
Optoisolators provide a low-impedance link between a control circuit and a power circuit
B
Optoisolators provide impedance matching between the control circuit and power circuit
C
Optoisolators provide an electrical isolation between a control circuit and the circuit being switched
D
Optoisolators eliminate the effects of reflected light in the control circuit
Correct Answer: Optoisolators provide an electrical isolation between a control circuit and the circuit being switched
