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 …
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 …
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 …
The volt-ampere characteristic of the PN-junction diode is a curve between the voltage over the junction and the circuit current. The circuit arrangement of the curve is shown in the figure below. The circuit arrangement shows that the resistor is connected in series with the PN junction diode to limit the forward bias current from …

Definition: The configuration in which the collector is common between emitter and base is known as CC configuration. In CC configuration, the input circuit is connected between emitter and base and the output is taken from the collector and emitter. The collector is common to both the input and output circuit and hence the name …

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 …
Definition: The configuration in which the emitter is connected between the collector and base is known as a common emitter configuration. The input circuit is connected between emitter and base, and the output circuit is taken from the collector and emitter. Thus, the emitter is common to both the input and the output circuit, and …
The voltage of the power system may vary with the change in load. The voltage is normally high at light load and low at the heavy-load condition. For keeping the voltage of the system in limits, some additional equipment requires which increase the system voltage when it is low and reduces the voltage when it …
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 …
When an electrical current passes through the body, the nervous system experience an electric shock. The intensity of the shock depends mainly on the strength of the current and the path taken by the current through the body and the duration of contact. In extreme cases the shock causes the failure of the normal action …
