Definition of AC Voltage:
The voltage which causes the alternating current is known as the alternating
voltage. AC refers to quantities that regularly change polarity at a frequency above
zero. The frequency of the AC voltage depends on the country (mostly 50 and 60
Hz are used). The power factor for AC voltage lies between 0 to1. The main
advantage of the AC voltage is that it is easily measured.
Definition of DC Voltage:
The dc voltages induce the direct current. The waves only in one direction and the
magnitude of the voltage always remain constant. The generation of the DC
voltage is quite simple and easy. The voltage induces by rotating the coil in the
field of the magnet. The coil consists the split ring and commutator which converts
the alternating voltage into the direct voltage.
