Mesh Current Equation

Mesh Current Equation: We have earlier discussed meth analysis but have applied it only to resistive circuits. Some of the ac circuits presented in this chapter can also be solved…

Reactive Power

Reactive Power and The Power Triangle: We know that the average power dissipated is From the impedance triangle shown in Fig. 6.4 If we substitute Eqs (6.12) and (6.13) in…

Apparent Power

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

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: 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: 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

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…
