Transistor Load Line Analysis

Definition: The load line analysis of transistor means for the given value of collector-emitter voltage we find the value of collector current. This can be done by plotting the output characteristic and then determine the collector current IC with respect to collector-emitter voltage VCE. The load line analysis can easily be obtained by determining the …

Operating Point in Transistor

 Definition: The point which is obtained from the values of the IC (collector current) or VCE (collector-emitter voltage) when no signal is given to the input is known as the operating point or Q-point in a transistor. It is called operating point because variations of IC (collector current) and VCE (collector-emitter voltage) takes place around this point when no …

Universal Relay Torque Equation

The universal torque equation explains the working of an electrical relay. The relay has some arrangement of electromagnetic. These electromagnetic consist current and voltage windings. The current through the winding produces magnetic flux. And the torque is produced by the interaction of the flux of the same winding or between the flux of both the windings. If …

NPN Transistor

Definition: The transistor in which one p-type material is placed between two n-type materials is known as NPN transistor. The NPN transistor amplifies the weak signal enter into the base and produces strong amplify signals at the collector end. In NPN transistor, the direction of movement of an electron is from the emitter to collector region due …

Difference Between kW & kWh

The most significant difference between the kW and kWh is that the KW measure the power generate and utilise by the devices, whereas the kWh measure the energy consumed by the electrical equipment. The other differences between kW and kWh are explained below in the comparison chart. The word demand shows the kW, and the word …
