Whether you are preparing for a technical interview or just testing your knowledge, these FAQ Questions will help you succeed.

What is a Potentiometer?

A potentiometer is a continuously variable rotating or sliding resistance.

What is the use of potentiometer?

Often a potentiometer is used as a linear resistance or linear voltage divider. They are commonly used to control electrical devices such as volume controls on audio equipment.

What is Circuit breaker

A two-terminal device designed to ensure that current levels do not exceed safe levels. If "tripped," it can be reset with a switch or a reset button

Define Efficiency?

A ratio of output to input power that provides immediate information about the energy-converting characteristics of a system.

How Crompton DC potentiometer differs from sliding contact wire potentiometer?

It consists rounded wire instead of straight wire.

How linear potentiometer works?

Resistor arranged with a fixed connection on each end and a sliding connection between the two ends, so that translation of the sliding connection alters the resistance between it and each end.

What do you mean by Calibration?

The process of adjusting an instrument or compiling a deviation chart so that its reading can be correlated to the actual value being measured.

What is the principle of Potentiometer?

The potential difference across any length of a wire of uniform cross-section and uniform composition is proportional to its length when a constant current flows through it.?

Define Sensitivity of a Potentiometer?

The sensitivity of the potentiometer depends upon the value of potential gradient K. (K=Potential supplied by main battery divided by length of wire) Smaller the value of K, smaller the potential difference that a potentiometer can measure and more is the sensitivity of the potentiometer.

State Ohms Law?

Ohms law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance

Define Power?

An indication of how much work can be done in a specified amount of time; a rate of doing work. It is measured in joules/second (J/s) or watts (W).

Define Resistance?

The electric property that impedes current; for ohmic materials, it is the ratio of voltage to current, R = V/I

What is a Rheostat?

An element whose terminal resistance can be varied in a linear or nonlinear manner.

What do you mean by Variable Resistor

A resistor whose resistance can be varied.

What do you mean by Voltage Drop

The amount of energy consumed when a device offers resistance in its circuit.

What is Varistor?

A voltage-dependent, nonlinear resistor used to suppress high-voltage transients.
