Analog Devices & Circuits

What is the purpose of a resistor in an electrical circuit?

• To store energy in an electrical circuit

• To amplify the signal in an electrical circuit

• To limit the flow of current in an electrical circuit

• To increase the voltage in an electrical circuit

How does the value of a capacitor affect its ability to store charge?

• The value of a capacitor, specifically its capacitance, directly affects its ability to store charge.

• The value of a capacitor does not impact its ability to store charge.

• A higher capacitor value decreases its charge storage capacity.

• Capacitors with lower values store more charge than those with higher values.

What is the unit of inductance for an inductor?

• Newton (N)

• Ampere (A)

• Henry (H)

• Joule (J)

Explain the function of a diode in a circuit.

• A diode functions as a one-way valve for electricity in a circuit, allowing current to flow in one direction while blocking it in the reverse direction.

• A diode functions as a temperature sensor in a circuit.

• A diode functions as a sound amplifier in a circuit.

• A diode functions as a wireless transmitter in a circuit.

What are the two main types of transistors?

• Phototransistor and Schottky Transistor

• Silicon-Controlled Rectifier (SCR) and Insulated-Gate Bipolar Transistor (IGBT)

• Bipolar Junction Transistor (BJT) and Field-Effect Transistor (FET)

• Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) and Darlington Transistor

How does a resistor limit the flow of current in a circuit?

• A resistor increases the flow of current by providing resistance.

• A resistor has no effect on the flow of current in a circuit.

• A resistor amplifies the flow of current in a circuit.

• A resistor limits the flow of current by providing resistance.

What happens when a capacitor is fully charged?

• It becomes a source of electrical power

• It loses all its stored energy

• It changes color

• It has stored the maximum amount of electrical energy possible.

Why is an inductor used in AC circuits?

• To reduce the voltage in the circuit

• To amplify the signal

• To store and release energy in the form of a magnetic field.

• To generate heat in the circuit

What is the symbol for a diode in a circuit diagram?

• Square

• Circle

• Arrow

• Triangle

Describe the difference between an NPN and PNP transistor.

• The main difference is the number of pins on the transistor

• NPN transistors are used for audio signals, while PNP transistors are used for video signals

• The difference is in the color of the casing

• The main difference between an NPN and PNP transistor lies in the arrangement of the layers and the doping types used.
