Question 1
Before measuring resistance through a heating element in a commercial appliance, what should the technician do first?
Correct Answer:
Disconnect power and isolate the element from the circuit
Explanation:
Resistance measurements are made on a de-energized circuit. Isolating at least one element lead prevents parallel circuit paths from distorting the reading.
Question 2
A technician needs to verify whether 240 V is actually applied to an energized heating element. Where should the voltmeter probes be placed?
Correct Answer:
Across the two element terminals
Explanation:
Voltage must be measured across the load. Measuring from each terminal to ground can be misleading because it does not show the potential difference across the element.
Question 3
Which instrument is most appropriate for measuring the operating current of a heater without opening the conductor?
Correct Answer:
Clamp ammeter
Explanation:
A clamp ammeter measures current by sensing the magnetic field around a single current-carrying conductor, so the circuit does not have to be opened.
Question 4
When using a clamp meter on a single-phase appliance cord, why should the clamp surround only one current-carrying conductor?
Correct Answer:
The magnetic fields of the outgoing and returning currents cancel
Explanation:
Equal current flows in opposite directions in the two conductors. If both are inside the clamp, their magnetic fields largely cancel and the meter reads near zero.
Question 5
A continuity test is being performed on a closed switch. What result normally indicates good continuity?
Correct Answer:
A very low resistance reading
Explanation:
A closed, healthy switch should provide a low-resistance path. An infinite or open reading indicates the current path is broken.
