Which of the following refers to a parallel circuit?
A. The current through each element is same
B. The voltage across element is in proportion to it's resistance value
C. The equivalent resistance is greater than any one of the resistors
D. The current through any one element is less than the source current
A. Apparent power is more than actual power
B. Reactive power is more than apparent power
C. Actual power is more than reactive power
D. Reactive power is more than actual power
The transient currents are associated with the
A. Changes in the stored energy in the inductors and capacitors
B. Impedance of the circuit
C. Applied voltage to the circuit
D. Resistance of the circuit
The inductance of a coil can be increased by
A. Increasing core length
B. Decreasing the number of turns
C. Decreasing the diameter of the former
D. Choosing core material having high relative permeability
Ave value/max value=0.637
Therefore, ave value=0.637*max value
=0.637 * 200 = 127.4V
Average value =2V/π=400/3.14=127.4
For sinusoidal waveform,
peak factor= peak value/ rms value =1.414
therefore rms value = 200/ 1.414 = 141.44
and form factor = rms value/ average value = 1.11
therefore, average value = 141.44/ 1.11 = 127.4 V
How the avg value is 127.4v from peak factor
Max. Value/avg value =1.414 so from this the avg value of voltage becomes 141.4v can u please give me the correct solution
