Hay’s Bridge

Definition: The Hay’s bridge is used for determining the self-inductance of the circuit. The bridge is the advanced form of Maxwell’s bridge. The Maxwell’s bridge is only appropriate for measuring the medium quality factor. Hence, for measuring the high-quality factor the Hays bridge is used in the circuit. In Hay’s bridge, the capacitor is connected …

Maxwell’s Bridge

Definition: The bridge used for the measurement of self-inductance of the circuit is known as the Maxwell bridge. It is the advanced form of the Wheatstone bridge. The Maxwell bridge works on the principle of the comparison, i.e., the value of unknown inductance is determined by comparing it with the known value or standard value. …

Wheatstone Bridge

Definition: The device uses for the measurement of minimum resistance with the help of comparison method is known as the Wheatstone bridge. The value of unknown resistance is determined by comparing it with the known resistance. The Wheatstone bridge works on the principle of null deflection, i.e. the ratio of their resistances are equal, and no current …

Light Emitting Diode (LED)

Definition: The LED is a PN-junction diode which emits light when an electric current passes through it in the forward direction. In the LED, the recombination of charge carrier takes place. The electron from the N-side and the hole from the P-side are combined and gives the energy in the form of heat and light. …

Electrostatic Deflection in CRT

Definition: Electrostatic deflection is the method of aligning the path of charged particles by applying the electric field between the deflecting plates. The word electrostatic means the strength and the direction of the field changes concerning time. So that, the particles will move only in one direction. The cathode ray tube uses deflecting plates for …
