One of the significant difference between the LVDT (Linear variable differential transformer) and the RVDT (Rotatory Variable Differential Transformer) is that the LVDT changes the linear motion into the alternating electrical signals whereas the RVDT translate the angular displacement into an electrical signal. The other differences between the LVDT and RVDT are shown below in …
The most significant difference between the active and reactive power is that the active power is the actual power which is dissipated in the circuit. Whereas, the reactive power is the useless power which only flows between the source and load. The other differences between the active and reactive power are explained below in the comparison …
Definition: The maximum demand indicator measures the maximum amount of power requires by the consumer at the particular interval of time. The indicator is designed in such a way so that they measure the base and peak load but unable to measures the sudden short-circuit or starting high current of the motor. It is designed …
Definition: The Hot Wire Anemometer is a device used for measuring the velocity and direction of the fluid. This can be done by measuring the heat loss of the wire which is placed in the fluid stream. The wire is heated by electrical current. The hot wire when placed in the stream of the fluid, …
The most significant difference between the Eddy current and Hysteresis loss is that the eddy current loss occurs because of the relative motion between the conductor and the magnetic field. Whereas the hysteresis loss occurs because of the reversal of the magnetism. The other differences between the hysteresis and the eddy current loss are explained …

Definition: The seismic transducer is used for measuring the vibration of the ground. The spring mass damper element and the displacement transducer are the two main component of the seismic transducer. The mass that connected to the damper element and spring without any other support is known as spring mass damper element. And the displacement …
The starter is a device which is used to start and run the motor. The most significant difference between the three point and the four-point starter is that in three-point starter the no voltage coil (NVC) is connected in series with the field winding whereas in four-point starter the NVC is directly connected to the …

Definition: The bridge which measures the unknown mutual inductance regarding mutual inductance such type of bridge is known as the Campbell bridge. The mutual inductance is the phenomenon in which the variation of current in one coil induces the current in the nearer coil. The bridge also used for measuring the frequency by adjusting the …
The rating is the load carrying capability of the machine. It shows the maximum value of the voltage at which the machine is designed, and the current consumption occurs at that voltage. The machines are always rated in watts. But the alternator and the transformer are the only machines which are rated in volt-amp (VA). Why …
Definition: The inductor is a passive component which stores the electrical energy in the magnetic field when the electric current passes through it. Or we can say that the inductor is an electrical device which possesses the inductance. The inductor is made of wire which has the property of inductance, i.e., opposes the flow of …
