Please explain why only half of the waves are kept for the voltage across compared to that across the AC voltage source.

Q: Current is being discussed. Technician A says that DC current is produced in a sine wave. Technician…

A: Ac current is alternating current which has both positive and negative values. Which means that AC…

Q: If a voltage spike lasts for 1.5 nanoseconds, what is the frequency of the spike?

A: Voltage spike is defined as sudden rise in voltage which is very higher than normal voltage for very…

Q: The waveforms show a voltage (v) and a current (i) for an AC circuit. The current signal has a value…

A:

Q: RB=2k0?

A: We need to tell about the meaning of given resistance

Q: For the waveform of Figure, determinea) Period  I got 100us b) Frequency  I got 10kHz c)…

A: a) Given time = 525usNumber of cycles for 525us =  5 cycle + 1/4 cycle = 5.25 cycle.So period =…

Q: If a voltage waveform has a peak voltage of 88.0V and 4.5% ripple, what is the minimum voltage

A: In this question we need to find the minimum voltage.

Q: = For the given figure, eo/ei

A: We define three mixed nodes (x1,x2,x3 ) in the given signal flow graph as below,

HVDC

HVDC stands for high voltage direct current in the electric power transmission system. The high voltage direct current system uses direct current (DC) for the transmission of electrical power through transmission lines in contrast with the alternating current that is the AC system. The HVDC is used to transmit bulk power point-to-point through long distances transmission lines. Power is rapidly transferred because the efficiency of transmission lines is greatly increased over long distances due to HVDC lines.
