Basic Electronics

Which of the following components limits the flow of electric current?

• Capacitor

• Diode

• Resistor

• Inductor

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

• Amplify signals

• Store electrical energy temporarily

• Prevent current flow

• Switch the circuit on and off

Which component stores energy in a magnetic field?

• Resistor

• Inductor

• Capacitor

• Transistor

Which material allows electricity to flow easily?

• Insulator

• Semiconductor

• Conductor

• Plastic

Which of the following is a semiconductor material commonly used in electronics?

• Copper

• Rubber

• Silicon

• Wood

Which material is used to prevent electric current from passing through?

• Silicon

• Rubber

• Aluminum

• Steel

What does a multitester NOT measure?

• Voltage

• Resistance

• Weight

• Current

Before using a multitester to measure resistance, you should:

• Set it to voltage mode

• Plug it into a power outlet

• Set it to ohms mode

• Use a capacitor first

Which component acts like a switch and can amplify current?

• Resistor

• Diode

• Transistor

• Inductor

What will a multitester show if a wire is broken and you test for continuity?

• A high resistance reading

• A beep sound

• A voltage drop

• No reading
