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
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.
DC is more dangerous because its magnitude doen't goes zero instantly after every half cycle as in case of AC .
yes it is 230 v is deadly, it doesn't matter if it's ac or dc. Some people say one is more dangerous than the other. That implies that there is some voltage, lower than 230 v, at which one will kill you but the other will not. There is no conclusive evidence for that, so it can't be said that ac is more dangerous than dc or vice versa.
ac because thats the accelerated current. and it has way higher voltage. dc direct current hs low voltage and wont hurt as bad
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.
no actually dc current is more dangerous than ac because dc is a direct current and has no current zero condition ,which is very dangerous and do not leave us if we get shock while ac current leave us when we get shock
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.
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.
