Electrical Circuit Design
Q1.How does an interlocking circuit ensure safety in controlling a DC motor's direction?
a. By increasing the motor's power
b.By reducing the current flow
c.By preventing both relays from being energized at the same time
d.By enhancing the motor's speed control
Q2.What is the function of the NO (Normally Open) push button in the control circuit?
a. To break the circuit when pressed
b. To close the circuit and energize the relay when pressed
c. To permanently close the circuit
d. To regulate the motor's speed
Q3.When the relay for the forward direction is activated, what happens in the circuit?
a. The motor runs in reverse
b.The motor stops
c.The current flows in the forward direction, and the motor runs forward
d.Both relays are activated
Q4.Which component in the interlocking circuit is directly responsible for ensuring that only one relay can be active at any time?
a. Relay coil
b. NC contacts of the opposite relay
c. Motor terminals
d. Power supply
Q5.What will occur if the NC (Normally Closed) push button is pressed while the motor is running?
a. The motor will increase its speed
b. The motor will continue to run in the same direction
c. The circuit will open, and the motor will stop
d. The motor will change direction
