Frequently Asked Questions – Electronic Components
What is a resistor?
A resistor is a component that limits the electrical current in a circuit. It is measured in ohms (Ω).
What is the purpose of a transistor?
A transistor acts as a switch or an amplifier. It is essential in both digital and analog circuits.
What is a capacitor?
A capacitor stores energy in the form of an electric charge and can release it quickly. It's used to filter, smooth, or delay signals.
What does a diode do?
A diode allows current to flow in only one direction. It protects circuits from reverse polarity.
What is an inductor (coil)?
An inductor stores energy in the form of a magnetic field. It’s used in filters, transformers, and power converters.
