AC - Alternating current , means the sign wave alternates +180 degrees to -180 degrees. this is the most common of power supplys , such as the power to your house etc.
DC - direct current , is a steady source of power on a straight wave form , although the wave can be altered , DC is mostly found in batteries or Rectifiers .
basically - power outlets kill
- batteries dont :D
What else can I help you with?
How you convert DC TO ac?
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.
What is the advantages of the universal motors?
the universel motor can runs at both ac and dc supply.
How can a radio use both DC and AC?
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.
What is the use of a regulator?
ac supply converted with dc supply
What is the use of regulator?
ac supply converted with dc supply
Is the metro rail train using ac or dc power supply?
dc power supply
Ac and dc load line of BJT-explain?
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.
Difference between ac and dc bridge?
DC Bridge... We use DC supply, Detector is also a DC current detector and we use only resistive components no need for wegner's earthing device balancing time is comparatively less.. where as in AC bridges opposite of above. i.e. AC supply, AC current detector resisitive+ reactive componants need for wagner's earthing device and balancing time is high as we use AC supply..
What are the key differences between AC and DC current, and how do these differences impact the efficiency of electrical systems?
AC (alternating current) and DC (direct current) differ in the direction of flow and voltage fluctuation. AC changes direction periodically, while DC flows in one direction. AC is more efficient for long-distance transmission due to lower energy loss, but DC is better for certain devices like electronics. The choice between AC and DC depends on the specific application and efficiency requirements of the electrical system.
How does DC to ac power supply work?
If having DC and AC is required then a PWM pulse width modulator is required to chop the DC to make AC
Why ac prepared DC current?
because the transmission cost of ac supply is lesser than dc. thats why ac is prefered
Can a DC series motor with speed control be connected on AC supply?
A dc series motor with speed control can be connected on ac supply because dc machines are totally reversible.
