In a Printed Circuit Board (PCB) layout, what do copper traces represent?

b) Connections between components

Integrated circuits (ICs) contain:

b) Multiple electronic components on a single chip

Transistors are used for:

b) Amplifying electronic signals

LEDs (Light Emitting Diodes) are used to:

b) Control the flow of current in one direction

A fuse is a safety device that:

b) Melts if excessive current flows through it

a) Controls the flow of current

How does a transformer work?

b) By changing voltage through electromagnetic induction

d) By storing electrical energy

What is the difference between a voltmeter and an ammeter?

c) Voltmeter measures voltage, ammeter measures current

d) Voltmeter measures resistance, ammeter measures current

When testing a capacitor with a multimeter, the ideal scenario is for the meter to:

a) Show a reading that slowly increases and holds steady

b) Show a reading that rapidly increases and then drops to zero

Resistors are used for:

c) Opposing the flow of current

The function of a capacitor is to:

b) Store electrical energy in an electric field

a) Control the flow of current in one direction

Smoke or a burning smell coming from a component during testing usually indicates:

c) The component is likely damaged

a) The component is functioning properly

b) A minor adjustment is needed

d) It's time for a coffee break

When troubleshooting a circuit, it's important to:

c) The presence of solder bridges

When replacing a component, it's crucial to ensure the replacement has the same:

b) Physical size (footprint) and specifications

A simple way to test an LED (Light Emitting Diode) is to:

a) Measure its resistance with a multimeter in diode mode

c) Visually inspect it for damage

b) Connect it directly to a high voltage source

Consulting a datasheet for a specific component is valuable because it provides information on:

b) Expected operating parameters and specifications

a) How to best remove it from the circuit

c) The manufacturer's contact information only

Safety precautions when testing electronic components include:

a) Using only one hand to avoid shocks
