What is the primary function of a resistor in a circuit?
A resistor limits the flow of electric current, protecting components from damage due to excessive current.
What is the purpose of a diode in a circuit?
A diode allows current to flow in only one direction, protecting the circuit from reverse voltage.
What does a capacitor do in an electronic circuit?
A capacitor stores electrical energy and releases it when needed, smoothing voltage fluctuations.
What is an inductor used for in an electronic circuit?
An inductor stores energy in a magnetic field when current passes through it and resists changes in current flow.
What is the function of a transistor in a circuit?
A transistor is used to amplify or switch electronic signals, serving as a basic building block in many electronic devices.
How do you calculate the total resistance in a series circuit?
In a series circuit, the total resistance is the sum of all individual resistances.

What is the typical application of a Zener diode?
A Zener diode is used for voltage regulation, allowing current to flow in the reverse direction when the voltage exceeds a certain value.
What does a multimeter measure?
A multimeter is used to measure voltage, current, and resistance in a circuit, making it a versatile tool for electronics troubleshooting.
What is the purpose of a fuse in an electronic circuit?
A fuse protects the circuit by breaking the connection if the current exceeds a safe level, preventing damage to components.
