FAQs on Electronic Devices Mock Test for JEE Main 2025-26: Free Online Practice
1. What is a semiconductor?
Semiconductors are materials whose electrical conductivity falls between conductors (like metals) and insulators (like glass). They show increased conductivity at higher temperatures and are mainly used in diodes, transistors, and integrated circuits. Common examples include silicon and germanium.
2. What is a PN junction diode?
A PN junction diode is an electronic device made by joining a P-type (positive) and N-type (negative) semiconductor material. It allows current to flow in only one direction and is widely used for rectification, signal modulation, and switching circuits.
3. Explain the difference between intrinsic and extrinsic semiconductors.
Intrinsic semiconductors are pure forms of semiconductor materials without any impurity. In contrast, extrinsic semiconductors are formed by adding impurities, a process called doping, to improve conductivity. Extrinsic types include n-type (with extra electrons) and p-type (with holes) semiconductors.
4. What is the application of a Zener diode?
A Zener diode is mainly used for voltage regulation in circuits. It allows current to flow in the reverse direction when the applied voltage exceeds the Zener breakdown voltage, thereby protecting devices from voltage fluctuations.
5. State two uses of transistors in electronic circuits.
Transistors are versatile components with two main uses:
- As amplifiers to increase the strength of weak signals.
- As switches in digital circuits to turn signals ON or OFF.
6. What is a rectifier? Name its types.
A rectifier is a device that converts alternating current (AC) into direct current (DC). The main types are: Half-wave rectifier, full-wave rectifier, and bridge rectifier. Each type ensures current flows in one direction for effective power supply.
7. Describe the working principle of a Light Emitting Diode (LED).
An LED works on the principle of electroluminescence. When a suitable voltage is applied in the forward direction, electrons and holes recombine, releasing energy in the form of visible light. LEDs are used as indicators and display lights due to their efficiency.
8. What is the function of a photodiode?
A photodiode is a semiconductor device that converts light energy into electrical current or voltage. It operates mainly in reverse bias and is used in light sensors, solar cells, and optical communication systems.
9. Explain the difference between forward and reverse bias in a diode.
Forward bias occurs when the positive terminal of a battery is connected to the P-side and the negative to the N-side of a diode, allowing current flow. Reverse bias means the connections are reversed, which blocks current except for a very small leakage current.
10. What is the logic gate? Name the basic logic gates.
Logic gates are digital electronic devices that perform logical operations on input signals to produce an output. The basic logic gates include: AND gate, OR gate, and NOT gate.
11. How do you differentiate between analog and digital signals?
Analog signals are continuous variations of voltage or current, representing physical quantities (e.g., sound, temperature). Digital signals are discrete, using binary values (0 and 1) to represent information, making them less susceptible to noise and distortion.
12. What is the importance of doping in semiconductors?
Doping is the addition of impurity atoms to a pure semiconductor to increase its conductivity. This process creates n-type or p-type semiconductors, enabling the creation of essential devices like diodes and transistors for modern electronics.
