Silicon and germanium can act as piezo resistive materials.
- True
- False
Correct Answer

A. True

Explanation

Silicon and germanium can act as piezo resistive materials because they exhibit a property called the piezo resistive effect. This effect refers to the change in electrical resistance of a material when it is subjected to mechanical stress or strain. Both silicon and germanium have a crystal lattice structure that allows them to experience this effect. When mechanical pressure is applied to these materials, it causes a change in their atomic arrangement, which in turn leads to a change in their electrical resistance. Therefore, it is true that silicon and germanium can act as piezo resistive materials.

- Sensitivity
Correct Answer

A. Sensitivity

Explanation

Sensitivity refers to the degree of response or change in the output of a sensor with a corresponding change in the input. It measures the ability of the sensor to detect and respond to variations in the input signal. A higher sensitivity means that even small changes in the input will result in a significant change in the output, while a lower sensitivity indicates that larger changes in the input are required to produce a noticeable change in the output. Therefore, sensitivity is the most appropriate term to describe the change in output of a sensor with a change in input.

What is the principle of operation of LVDT?
- Mutual inductance
- Self-inductance
- Permanence
- Reluctance
Correct Answer

A. Mutual inductance

Explanation

The principle of operation of LVDT is based on mutual inductance. LVDT stands for Linear Variable Differential Transformer, which is a type of electromechanical transducer used for measuring displacement or position. It consists of a primary coil and two secondary coils wound on a cylindrical core. When an AC voltage is applied to the primary coil, it induces a voltage in the secondary coils due to mutual inductance. The displacement of the core changes the mutual inductance between the primary and secondary coils, resulting in a change in the output voltage. Therefore, mutual inductance is the principle that allows LVDT to accurately measure linear displacement.

When temperature rises, resistance of negative temperature coefficient thermistor
- Increases
- Decreases
- Zero
- Infinity
Correct Answer

A. Decreases

Explanation

When temperature rises, the resistance of a negative temperature coefficient (NTC) thermistor decreases. This is because NTC thermistors are made of semiconductor materials that exhibit a decrease in resistance as temperature increases. As the temperature rises, the increased thermal energy causes more electrons to be released, increasing the conductivity of the material and resulting in a decrease in resistance.

With the increase in the intensity of light, the resistance of a photovoltaic cell
- Increases
- Decreases
- Remains same
- None of these
Correct Answer

A. Decreases

Explanation

As the intensity of light increases, the resistance of a photovoltaic cell decreases. This is because the photovoltaic cell converts light energy into electrical energy. When the intensity of light is high, more photons are absorbed by the cell, leading to a greater number of electron-hole pairs being generated. This increases the conductivity of the cell, resulting in a decrease in resistance. Therefore, the resistance of a photovoltaic cell decreases with an increase in light intensity.

- 2.5 mA
- Between 3 to 35 mA
- 25 mA
Correct Answer

A. Between 3 to 35 mA

Explanation

The correct answer is "Between 3 to 35 mA" because LEDs typically require a current within this range to operate efficiently. Operating the LED at a current below 3 mA may result in dim or no illumination, while exceeding 35 mA can lead to overheating and damage to the LED. Therefore, it is necessary to provide a current between 3 to 35 mA to ensure proper functioning and longevity of the LED.

Correct Answer

A. Selenium

Explanation

Selenium is used in photoconductive cells. Photoconductive cells are devices that change their electrical conductivity when exposed to light. Selenium is a semiconductor material that exhibits this property, making it suitable for use in photoconductive cells. When light falls on selenium, it excites its electrons, causing an increase in electrical conductivity. This property allows selenium to be used in light sensors, solar cells, and other light-sensitive applications. Quartz and Rochelle salt do not possess the same photoconductive properties as selenium, making them unsuitable for use in photoconductive cells.

What is the relation between scale factor and sensitivity of a transducer?
- Scale factor is double of sensitivity
- Scale factor is inverse of sensitivity
- Sensitivity is inverse of scale factor
- Sensitivity is equal to scale factor
Correct Answer

A. Scale factor is inverse of sensitivity

Explanation

The scale factor of a transducer refers to the ratio of the output signal to the input signal, while the sensitivity of a transducer refers to the change in output signal per unit change in input signal. In this case, the correct answer states that the scale factor is the inverse of sensitivity. This means that as the sensitivity of the transducer increases, the scale factor decreases, and vice versa. In other words, a higher sensitivity will result in a smaller scale factor, indicating a greater change in output signal for a given change in input signal.

The linear variable differential transformer transducer is
- Inductive transducer
- Non-inductive transducer
- Capacitive transducer
- Resistive transducer
Correct Answer

A. Inductive transducer

Explanation

The linear variable differential transformer (LVDT) is an inductive transducer. It operates based on the principle of electromagnetic induction. The LVDT consists of a primary coil and two secondary coils wound on a cylindrical core. When an AC voltage is applied to the primary coil, it induces a voltage in the secondary coils. The magnitude of the induced voltage in the secondary coils is directly proportional to the displacement of the core. Therefore, the LVDT is used to measure linear displacement by converting it into an electrical signal through inductive coupling.
