What is the gereral references difference between ac and dc?
AC is mainly having frequency i.e., cycles per second.as the name suggest that it is alternating current DC is not having any cycles so, it is not having frequency
What is the difference between a voltage converter and a voltage inverter?
Converter is AC to DC. Inverter is DC to AC
What is use of RFC in Hartley oscillator?
it is a radio frequency choke which connects the dc supply to the circuit but isolate the dc supply from the high frequency oscillations generated in the feedback circuit
Well you can say that the frequency of DC is constant or not?
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.
How do you change the speed of motor without change pole and frequency?
On an AC motor you basically vary the frequency on a DC you can vary the voltage.
What is the gereral references difference between ac and dc?

What is frequency of dc?
You can say DC voltage has a frequency of zero Hz.Because it is unidirectional in nature (may be positive or negative)
What is the frequency of 27 DC volts?
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.
Why use DC circuit when frequecy is zero?
DC has no frequency.
What is frequency in relation to a battery?
dc does not have frequency only ac
What is the Difference between frequency converter and frequency inverter?
frequency is genrally cycle per second, and frequencies may be of a dc nature or ac , devices which convert dc frequency in to an ac frequency are frequency converters and devieces which convert ac frequency in to dc frequency are frequency inverters. because in terms of power electronics, devices which convert ac to dc are called converters, and devices which convert dc in to ac are called "inverters" 'mehboob hunzai" I'm a engineers in this devices, the frequency inverter is convert AC to AC but with variable frequency output, means the frequency & voltage are adjustable; The frequency converter can convert DC to AC, like 24VDC to 220VAC and also the frequency is adjustable. One most important thing is the out power of frequency inverter just can be used for controlling AC motor, while frequency converter can be treated as normal power supply as our daily using power grid.

Skin effect related to ac and DC?
IT IS RELATED TO AC ONLY BKZ SKIN EFFECT DEPENDS FREQUENCY ONLY WHERE IS IN DC NO FREQUENCY
Is lighting AC or DC?
Mostly DC, but there is high frequency AC too.
Speed of DC Motor can be controlled by a frequency variable?
by using a frequency tuner in input we can change input frequency and in this way speed of dc motor will also vary. <<>> Varying the frequency (VFD) only works on AC motors.
What is the difference between current (DC) and alternating current (AC)?
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.
What is the difference between a voltage converter and a voltage inverter?
Converter is AC to DC. Inverter is DC to AC
When does a capacitor act as a resistor of infinite resistance?
When the frequency is zero(i.e when dc power is supplied), capacitor is open is treated as open circuit having infinite resistance.
