Apparent Power and Power Factor: Apparent Power - The power factor is useful in determining useful power (true power) transferred to a load. The highest power factor is 1, which…
Average Power Formula: To find the average value of any power function, we have to take a particular time interval from t1 to t2; by integrating the function from t1…
Instantaneous Power Formula: Instantaneous Power Formula - In a purely resistive circuit, all the energy delivered by the source is dissipated in the form of heat by the resistance. In…
Phase Relation in Pure Resistor: Phase Relation in Pure Resistor - When a sinusoidal voltage of certain magnitude is applied to a resistor, a certain amount of sine wave current…
Two Port Network Articles: Terminal Pairs or Ports: A pair of terminals at which an electrical signal may enter or leave a network is called a port. The terminals or…
Network Topology in Network Analysis Articles: Indefinite Admittance Matrix: Consider Indefinite Admittance Matrix of a linear network with n terminals as shown in the Fig. 5.26. Let us consider a…
Attenuator Network: An attenuator network must fulfil following conditions. It must give correct input impedance, It must give correct output impedance and It must provide specified attenuation. In general, attenuation…
