In AC circuits (regular household circuits), the voltage source changes the polarity of its output regularly. In India, this happens 100 times per second. By contrast, in DC circuits, the current flow is unidirectional due to the fixed polarity of the voltage source. This leads to undisrupted, longer and sustainable arcs in DC circuits (the reason why arc welding machines use DC current and not AC current).
While breaking a DC circuit, it is easy to form such arcs, and if they are not extinguished in time they lead to device overheating and ultimately to fire. AC circuit breakers are not equipped well enough to deal with such arcs, whereas DC circuit breakers have special arc chutes to capture arcs and extinguish them safely, hence they are highly recommended.
dc ammeter has three connecting pins while ac has four
well the difference mainly exists in the method of finding them , these are :-1. in finding DC load line :-open all AC sourcesopen all the capacitors2. for AC load line:-open all the Dc sourcesshort all the capacitors.
A capacitor is a capacitor, no matter what circuits you use it in. There is no difference between one used in AC and one in DC, except perhaps the size that is appropriate.
i think Transformer operates AC and ferrite core operates in DC
There's no correlation between the voltage, the current, and whether the source is AC or DC.
There is no difference between AC AND DC chockes
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
AC rises with respect to time but DC is steady.
magneto is dc
dc ammeter has three connecting pins while ac has four
AC power is made by alternating current and DC does not change.
ac comes directly from the power socket, and DC is battery source. Answer2: The frequency is the difference, AC has frequency f>0 and DC does not f=0.
The voltage source that is applied to them is the difference between AC and DC light bulbs.
Converter is AC to DC. Inverter is DC to AC
a magneto puts out dc electricity
The major difference between an AC generator and a DC generatoris that the DC generator requires a mechanism to provide a DC output. This can be done mechanically with a commutator or electronically with a rectifier. Internally, all generators produce an alternating voltage. Allgeneratorsrequire a magnetic field.
