Understanding Electronic Circuits

What is the function of a resistor in a circuit?

• To convert electrical energy into heat energy.

• To increase the current flow in a circuit.

• To limit current and control voltage in a circuit.

• To store electrical energy in a circuit.

Explain the difference between series and parallel circuits.

• Series circuits have multiple paths for current, while parallel circuits have a single path.

• In series circuits, the voltage is divided, while in parallel circuits, the current is divided.

• Series circuits can operate independently, while parallel circuits cannot.

• Series circuits have a single path for current, while parallel circuits have multiple paths.

What is Ohm's Law and how is it applied in circuits?

• Ohm's Law is V = I * R, relating voltage, current, and resistance in circuits.

• Ohm's Law states that current is equal to voltage divided by resistance.

• Ohm's Law is used to calculate power in a circuit as P = V + I.

• Ohm's Law only applies to alternating current (AC) circuits.

Define the term 'capacitor' and its role in electronic circuits.

• A capacitor is a device that stores electrical energy and is used in electronic circuits for filtering, smoothing, and energy storage.

• A capacitor is primarily used for generating electrical signals in circuits.

• A capacitor is a device that converts electrical energy into mechanical energy.

• A capacitor is a type of resistor used to limit current flow.

What are the basic components of a transistor and their functions?

• The basic components of a transistor are the emitter, base, and collector.

• Anode, cathode, and gate

• Input, output, and ground

• Source, drain, and substrate
