Q1Domain Verified
A technician is troubleshooting a series circuit containing a resistor and an LED. The LED is not illuminating, but the resistor shows a voltage drop. Which of the following is the most likely cause of the LED failure, assuming the power source is functional?
The LED is open-circuite
D) The power supply voltage is too low.
The resistor has an open circuit.
The LED is short-circuited.
Q2Domain Verified
A mechanic is installing a new motor that draws 15A at 240V. The existing wiring is protected by a 20A circuit breaker. If the motor experiences a temporary surge in current during startup, what is the most probable outcome for the circuit breaker?
The circuit breaker will not trip as the surge is temporary and within the breaker's tolerance.
The wiring will overheat before the circuit breaker trips.
The circuit breaker will trip immediately due to the surge exceeding the nominal current.
The circuit breaker will trip after a short delay, protecting the circuit from the sustained surge.
Q3Domain Verified
A technician is measuring the AC voltage across a capacitor in a power supply filter circuit. The multimeter reads 120V AC, but the DC voltage across the capacitor is only 5V DC. What does this indicate about the capacitor's condition?
The capacitor has a high ESR or has significantly degraded its capacitance.
The capacitor has a low equivalent series resistance (ESR).
The capacitor is functioning normally and effectively filtering the AC ripple.
The capacitor has failed open, preventing it from storing charge.
