Frequency with AC is how many times in one second it goes thru a cycle of reversing polarity twice.
DC does not reverse, in other words the frequency is zero.

What are the touch voltage for DC and AC limits in Australia?
315kva 450v AC
What makes a dc bulb different from an ac bulb?
The voltage source that is applied to them is the difference between AC and DC light bulbs.
Does ac dc mean it can run on battery or plug into wall?
AC - Alternating Current, same thing that comes out of a wall socket DC - Direct Current, batteries. <<>> When a device has AC/DC on its name plate, it can work off either of the two voltages. Many portable radios have this function. When the radio is plugged into AC, the voltage is transformed to the working DC voltage and then rectified to a DC voltage. When the radio is on battery operation, the radio operated strictly from the DC voltage supplied by the batteries. The change between voltages from AC to DC or DC to AC is almost instantaneously. This change over is done through an AC powered relay in the radio. When the AC held in relay looses its supply it de energizes and switches over to DC power if the batteries are in the radio. With batteries in the radio try it. Plug into the AC supply, turn on the radio that has batteries installed in it, unplug the AC supply and the radio will not miss a beat.
Do batteries provide a DC voltage or an AC voltage?
Batteries produce DC because the potential difference is determined by the chemical reaction inside the battery. This voltage is constant.
Can one get shocked by DC voltage?
unfortunately yes! A DC voltage is potentially more dangerous than an AC voltage due to the fact that ac swings from positive to negative and therefore passing zero volts in the process. If you were say, holding a piece of metal with AC across it you have more chance of letting go than holding the same piece with DC across it. DC is "constantly on" if you like... be careful!
How do you convert 23 voltage DC to 230 Voltage AC?
How do you convert 23 voltage DC to 230 Voltage AC?
Can you measure ac mains voltage with dc voltmeter or high dc voltage with ac meter?
You cant.
ABS sensor produce AC voltage or DC voltage?
AC !
What is the output voltage of megger is it ac or DC?
megger are available in ac &dc
Can you connect an AC source in series to DC source - then what happens to the current under a steady state condition?
With an AC and a DC voltage source in series, the DC voltage can be added to the RMS value of the AC voltage to give the effective voltage.
Is DC voltage and average voltage same?
no, dc volatage is a type of current direct current, ac is alternating current, average voltage could be any type of voltage ac or dc that maintains a constant rangeAnswerNo. A DC voltage is exactly equivalent to an AC rms-voltage. So, for example, 100 V (DC) is exactly equivalent to 100 V (AC rms). The average value of an AC waveform is zero.
Is DC is at low voltage than ac?
There's no correlation between the voltage, the current, and whether the source is AC or DC.
Why smps convert ac to dc and again to dc to dc?
first it converts ac to dc as rectifier But the required dc voltage is obtained by taking average of on & off DC input voltage.
How do you make ac into DC in a ac transformer?
You can not change AC into DC using a transformer. A transformer changes the voltage levels. To change AC into DC, you would need a rectifier. To change that into smooth DC you need a capaciter and a voltage regulater
Why is rectification needed?
To convert AC voltage to DC voltage.
What is the difference between a voltage converter and a voltage inverter?
Converter is AC to DC. Inverter is DC to AC
How do you conyert AC to DC?
You rectify AC voltage through a diode bridge to convert it to DC.
