A. End-to-end return loop
B. No end-of-line resistor
C. Open circuit monitoring only
D. Two power supplies
Answer: A
Rationale: Class B circuits are supervised but do not return to the panel.
4. What is the purpose of an end-of-line resistor?
A. Increase voltage
B. Supervise circuit integrity
C. Reduce current
D. Ground the circuit
Answer: B
Rationale: It allows the panel to monitor circuit continuity.
