Explanation

For measuring small resistance, we use the Kelvin Bridge.

This bridge is designed to provide accurate measurements of very low resistances by compensating for the resistance of the measuring leads.

Explanation

A refrigerator takes heat from low temperature and removes it to high temperature.

It transfers heat from the interior (low temperature) to the exterior (high temperature) to maintain a cool environment inside.

Explanation

The easiest way to shift the load between two parallel shunt generators is to adjust their field rheostats.

This adjustment changes the excitation of the generators, thereby controlling the distribution of the load.

Explanation

SCR (Silicon Controlled Rectifier) is a unidirectional device.

It allows current to flow in only one direction, from anode to cathode.

It is controlled by a gate signal.

Explanation

The terminal voltage of a generator changes due to armature resistance.

The voltage drop across the armature resistance affects the terminal voltage as the load current varies.

Explanation

The 8085 is the modern version of the 8080 microprocessor.

It is an improved version with additional features.

Such as an integrated clock oscillator and three additional instructions.

Explanation

The principle of Superposition Theorem is used to analyze faults in a power system.

It allows for the analysis of complex faults by considering the effects of each fault condition individually and then summing the results.

Explanation

The transducer which converts physical quantities to pulses is called a Digital Transducer.

It outputs a digital signal or pulse train that corresponds to the measured physical quantity.

Explanation

In the left-hand rule, the thumb represents the direction of the force on the conductor.

This rule is used to determine the force experienced by a current-carrying conductor within a magnetic field.

Explanation

Power is calculated using P = V × I.

Here, I = 51.2 mA = 0.0512 A, so P = 220 V × 0.0512 A = 11.26 W.
