Power delivered to load calculated by five-point method can be equal to __________ (Pac is power delivered to load without distortion and D is the RMS of all Harmonic distortion)

Correct Answer: Pac (1+D2)
The equation of power delivered to load is same whether it is calculated by three-point or five point. The only difference is the calculation of D.

What is the total harmonic distortion if the amplitude of first harmonic distortion is 20dB and second harmonic distortion 25dB?

What is the total harmonic distortion if the amplitude of first harmonic distortion is 20dB, second harmonic distortion 25dB and external noise is 10dB?

A step-down delta-star transformer, with per-phase turns ratio of 5 is fed from a 3-phase 1100 V source. The secondary of this transformer is connected through a 3-pulse type rectifier, which is feeding an R load. The power delivered to the load is 6839.3 Watts. The maximum value of the load current is √2 x 22 A. Fin, the rms value of output voltage Vo (rms)

If Vr is the rms value of the inverter output voltage and V1 is the rms value of the fundamental component, then the total harmonic distortion (THD) is given by 1/2 d) 2

Public Affairs Centre (PAC) engages in action research focussing on Sustainable Development Goals in the context of India. PAC situated in-?

The ratio of the RMS amplitude of the higher order harmonic frequencies to the RMS amplitude of the fundamental frequency is commonly called __________

Power delivered to load is _________ with an increase in harmonic distortion.

A transformer has a primary voltage of 120 V rms and a secondary voltage of 25 V rms. If the secondary current is 1A rms, what is the primary current?

In a parallel RL circuit, there are 3 A rms in the resistive branch and 3 A rms in the inductive branch. The total rms current is

In a series RC circuit, 12 V(rms) is measured across the resistor and 15 V(rms) is measured across the capacitor. The rms source voltage is
