frequency if it will not zero then we cant tell its dc ...
AnswerFrequency is the number of alternations per unit time. As d.c. doesn't alternate, then zero divided by any quantity of time is zero!
You can say DC voltage has a frequency of zero Hz.Because it is unidirectional in nature (may be positive or negative)
Yes DC is periodic with zero frequency........and undefined fundamental time period To........
A DC ammeter will read zero
Inductive reactance is a resistance by inductors to the change of current flow, and is dependent on the frequency at which the current oscillates. DC current flows in only one direction so an inductor's impedance remains the same.
While it is true that an inductor opposes the flow of an alternating current, it does not necessarily 'block it'. The quantity that opposes the flow of an AC current is the inductor's inductive reactance, expressed in ohms. Inductive reactance is proportional to the frequency of the supply voltage and, at 50 or 60 Hz, the reactance of a transformer's winding is relatively low (although very much higher than its resistance) and, while this acts to limit the amount of current flow, it certainly doesn't act to block that flow.

Yes it is constant at Zero Frequency. No, DC or Direct Current only means that the current only goes one direction, but it can have a frequency. You can have a square wave, sawtooth wave or sine wave that never goes from positive to negative or negative to positive and it would be a direct current with a frequency.
DC has no frequency.
In case of DC: because the frequency of dc current is zero capacitive reactance ( Xc) = 1/2(22/7)fc f= frequency c=capacitence and when Xc=0 this implies that I=0 In case of AC: Xc >0 => I>0
Basically, "frequency" applies to AC, not to DC. If you want to assign it a frequency, the frequency is zero. The amount of volts is not relevant.
Frequency, as regards voltage, is a term applied to changes in the voltage per unit of time. As the voltage of the DC (direct current) supply does not change, it does not "cycle" like an alternating current (AC) supply. The frequency of oscillation of the voltage is zero cycles per second, or zero Hertz.
As far as know, frequency is not complex and is a positive number denoted in cycles per seconed like 60 cps. 0 cps is sometimes noted as DC, direct current with frequency of zero.
Zero = Nothing = Nil = 0 Hertz or Cycles per Second Direct Current is just as its name says: it does not alternate so it does not have any "frequency".

There is only one type of direct current and its 'frequency' is zero.
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.
DC, or direct current, is stronger than AC, or alternating current. The reason for this is because DC current is smooth and unvariable as opposed to AC which varies from zero to whatever the maximum is, and then goes back to zero once again.
