To operate DC and AC load with the help of Push to ON Switch and a Switching Relay

Q1. How does the relay protect the control circuit from the high-power load circuit?

a. By using a resistor to limit the current

b. By using a diode

c. By isolating the control circuit through electromagnetic operation

d. By grounding the control circuit

Q2. What does NO and NC mean with respect to Push buttons?

a. Normal operation and normal circuit

b. Normally On and normally closed

c. The IGBT is slower than a BJT

d. Normally open and normally closed

a. DC load

b. AC load

c. Resistive load

d. Inductive load

Q4. What is the expected behaviour of the relay when the Push to ON switch is pressed and held?

a. Relay de-energizes

b. Relay toggles between energized and de-energized state

c. Relay energizes and stays energized

d. Relay operates with a delay

Q5. FWhat is the expected state of the relay when both Push to ON and Push to OFF switches are not pressed?

a. Relay remains energized

b. Relay remains de-energized

c. Relay toggles between states

d. None of the above
