Q: Which tool is primarily used for measuring voltage, current, and resistance on a PCB?

Multimeter — A multimeter is the most versatile and commonly used tool for basic PCB testing.

Q: What setting on a multimeter is used to check for continuity in a circuit?

Diode/Continuity Test — The diode/continuity test setting emits a beep if there's a low-resistance path, indicating continuity.

Q: What should you do before touching any components on a PCB to prevent ESD damage?

Ground yourself using an ESD wrist strap — Grounding yourself discharges static electricity, protecting sensitive components from ESD.

Q: Which of these components is best tested with a diode test setting?

Diode — The diode test confirms the forward voltage drop and reverse blocking behavior of a diode.

Q: What does a short circuit on a PCB usually indicate?

Low resistance path between two points — A short circuit offers very little resistance, allowing excessive current to flow.

Q: What is the primary function of a capacitor in a circuit?

Storing electrical energy — Capacitors store energy in an electric field and release it later.

Q: How can you test a resistor with a multimeter?

Measure its resistance — Resistors are tested by measuring their resistance value using the ohms setting.

Q: What is the unit of measurement for resistance?

Ohms (?) — Resistance is measured in Ohms.

Q: What can a visual inspection help identify on a PCB?

All of the above — Visual inspection can reveal various physical damages, including shorts, cracks, and burns.

Q: Which tool is best suited for viewing signal waveforms?

Oscilloscope — An oscilloscope visualizes electrical signals changing over time.

Current is the measurement of the flow of electrical charge.

Question 14 of 15

What is the purpose of a magnifying glass when inspecting PCBs?

Magnifying glasses help to identify visual defects and smaller component details.

Question 15 of 15

What is the best way to determine if a trace is broken on a PCB?

A broken trace will show infinite resistance when tested using the resistance setting.
