Q: Which electronic component is designed to oppose the flow of current?

Resistor — Resistors limit current flow based on their resistance value.

Q: What is the unit of measurement for electrical resistance?

Ohm (?) — Resistance is measured in Ohms, named after Georg Ohm.

Q: Which component stores electrical energy in an electric field?

Capacitor — Capacitors store energy by accumulating charge on their plates.

Q: What is the function of a diode?

To block current flow in one direction — Diodes allow current in only one direction, acting as a one-way valve.

Q: What is the primary function of a transistor?

To switch or amplify electronic signals — Transistors are used as switches or amplifiers for electronic circuits.

Q: Which component opposes changes in current flow?

Inductor — Inductors store energy in a magnetic field and oppose current changes.

Q: What is the unit of measurement for capacitance?

Farad (F) — Capacitance is measured in Farads, named after Michael Faraday.

Q: What is the unit of measurement for inductance?

Henry (H) — Inductance is measured in Henrys, named after Joseph Henry.

Q: Which component is used to convert AC to DC?

Diode bridge — A diode bridge rectifies AC, allowing current flow in only one direction.

Q: Which component is commonly used in oscillators?

All of the above — Oscillators often rely on combinations of all these components.
