What is Ripple and Ripple Factor? – Formula of Ripple Factor

What is Ripple? Ripple is the fluctuating AC component present in rectified DC output. The output of a rectifier may either be DC current or voltage. In view of this, AC fluctuating component present in DC output voltage is called voltage ripple and that in DC current output is called current ripple. Why Ripple is … Read more What is Ripple and Ripple Factor? – Formula of Ripple Factor

Average Value of AC Current – Definition, Formula and Application

Definition Average value of AC or alternating current is expressed by that DC current which transfers across any point of circuit the same charge as is transferred by the AC current for the same time. This means, if AC current I in a circuit flows for t sec and charge Q is transferred across any … Read more Average Value of AC Current – Definition, Formula and Application

Root Mean Square or RMS Value of AC – Definition, Formula and Calculation

Definition Root Mean Square (RMS) value of AC current is defined as the steady or DC current which when flowing through a circuit for a given time period produces the same heat as produced by the AC current flowing through the same circuit for the same time period. RMS value is also known as effective … Read more Root Mean Square or RMS Value of AC – Definition, Formula and Calculation

Triplen Harmonics – Why are they in phase?

Definition: Triplen harmonics are the odd integral multiple of third harmonic wave. If the frequency of third harmonic wave is ω then frequency of triplen harmonic wave will be 3nω, where n = 3,5,9,…These waves posses a special characteristics and hence it becomes important for the study and analysis of power system. The amazing property … Read more Triplen Harmonics – Why are they in phase?

Poor Power Factor – Effects and Disadvantage

Effect of Poor Power Factor: The major effect of poor power factor is higher value of line current. We know that power factor (pf) is an important parameter for calculation of power in an AC circuit. For a given power and voltage, the current flowing through the line is inversely proportional to the power factor. … Read more Poor Power Factor – Effects and Disadvantage
