Which of the following is NOT a fundamental unit in the International System of Units (SI)?

  1. Meter (m)

  2. Kilogram (kg)

  3. Second (s)

  4. Ampere (A)

  5. Kelvin (K)


Correct Option: E
Explanation:

Kelvin is the SI unit of thermodynamic temperature, not a fundamental unit.

What is the SI unit of electric charge?

  1. Coulomb (C)

  2. Ampere (A)

  3. Volt (V)

  4. Ohm (Ω)

  5. Farad (F)


Correct Option: A
Explanation:

Coulomb is the SI unit of electric charge, representing the amount of charge carried by one electron.

Which of the following is a type of semiconductor material?

  1. Silicon (Si)

  2. Germanium (Ge)

  3. Gallium Arsenide (GaAs)

  4. Copper (Cu)

  5. Aluminum (Al)


Correct Option: A
Explanation:

Silicon is a widely used semiconductor material due to its abundance, relatively low cost, and well-understood properties.

What is the name of the phenomenon where a semiconductor material exhibits a decrease in resistance with increasing temperature?

  1. Superconductivity

  2. Negative Resistance

  3. Conduction

  4. Insulation

  5. Semiconduction


Correct Option: B
Explanation:

Negative Resistance is a phenomenon where a semiconductor material's resistance decreases with increasing temperature, unlike metals which exhibit positive resistance.

Which of the following is NOT a type of electromagnetic wave?

  1. Radio Waves

  2. Microwaves

  3. Infrared Radiation

  4. Ultraviolet Radiation

  5. Sound Waves


Correct Option: E
Explanation:

Sound waves are mechanical waves, not electromagnetic waves.

What is the name of the device that converts electrical energy into mechanical energy?

  1. Motor

  2. Generator

  3. Transformer

  4. Capacitor

  5. Resistor


Correct Option: A
Explanation:

A motor is a device that converts electrical energy into mechanical energy, causing rotation or linear motion.

Which of the following is NOT a type of electrical circuit?

  1. Series Circuit

  2. Parallel Circuit

  3. Open Circuit

  4. Short Circuit

  5. Closed Circuit


Correct Option: C
Explanation:

An open circuit is not a type of electrical circuit because it lacks a complete path for current flow.

What is the name of the phenomenon where an electric current flows through a material without encountering any resistance?

  1. Superconductivity

  2. Conduction

  3. Insulation

  4. Semiconduction

  5. Resistance


Correct Option: A
Explanation:

Superconductivity is the phenomenon where an electric current flows through a material without encountering any resistance, typically occurring at very low temperatures.

Which of the following is NOT a type of electronic device?

  1. Transistor

  2. Diode

  3. Resistor

  4. Capacitor

  5. Battery


Correct Option: E
Explanation:

A battery is an energy storage device, not an electronic device.

What is the name of the device that controls the flow of current in a circuit?

  1. Switch

  2. Fuse

  3. Relay

  4. Circuit Breaker

  5. Transistor


Correct Option: A
Explanation:

A switch is a device that controls the flow of current in a circuit by opening or closing the circuit.

Which of the following is NOT a type of electronic signal?

  1. Analog Signal

  2. Digital Signal

  3. Continuous Signal

  4. Discrete Signal

  5. Periodic Signal


Correct Option: C
Explanation:

Continuous Signal is not a type of electronic signal because it does not have discrete values.

What is the name of the phenomenon where a material exhibits a change in its electrical resistance when exposed to light?

  1. Photoconductivity

  2. Photoemission

  3. Photovoltaic Effect

  4. Electroluminescence

  5. Fluorescence


Correct Option: A
Explanation:

Photoconductivity is the phenomenon where a material exhibits a change in its electrical resistance when exposed to light.

Which of the following is NOT a type of electronic communication system?

  1. Radio

  2. Television

  3. Telephone

  4. Computer Network

  5. Satellite


Correct Option: D
Explanation:

Computer Network is not a type of electronic communication system because it does not transmit information through electromagnetic waves.

What is the name of the device that converts mechanical energy into electrical energy?

  1. Motor

  2. Generator

  3. Transformer

  4. Capacitor

  5. Resistor


Correct Option: B
Explanation:

A generator is a device that converts mechanical energy into electrical energy, typically through electromagnetic induction.

Which of the following is NOT a type of electronic display technology?

  1. Liquid Crystal Display (LCD)

  2. Light Emitting Diode (LED)

  3. Plasma Display Panel (PDP)

  4. Cathode Ray Tube (CRT)

  5. Inkjet Printer


Correct Option: E
Explanation:

Inkjet Printer is not a type of electronic display technology because it does not display information electronically.
