ac because thats the accelerated current. and it has way higher voltage. dc direct current hs low voltage and wont hurt as bad
Dc invereters are not well suited as compared to ac inverters.This is due to the reason because ac inverters are more efficient ,less dangerous and good for supply over distance.
we can convert a dc supply to an ac supply using inverters. Its a common operation which we observe in our daily lives dc can be converted to Ac using an undulator.
the universel motor can runs at both ac and dc supply.
Radios use DC power supplies to operate. If a radio is powered from a mains AC supply, a power supply circuit will convert the AC supply to DC. Therefore, a radio may have both a DC and an AC power input but ultimately, the internal circuitry will always use DC.
A: DEFINITELY DC since current is steady at whatever voltage while AC must have a less voltage as is supplied. Also at hi frequency the AC will the tendency to flow on the skin as opposed to flow internally
ac supply converted with dc supply
ac supply converted with dc supply
dc power supply
when the dc supply given, dc load line lies in the Ic and Vcc. when the AC supply given, AC load line lies in the Ic and Vcc.
If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC
because the transmission cost of ac supply is lesser than dc. thats why ac is prefered
A dc series motor with speed control can be connected on ac supply because dc machines are totally reversible.
