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 range
AnswerNo. 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.
What else can I help you with?
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.

What voltage is DC?
A voltage DC(direct current voltage) is a uni-direction steady voltage. It is the opposite of an analog/alternative voltage which varies in polarity and direction with time.
Will AC voltage or DC voltage have higher illumination intensity when provided at the same voltage?
Is this a trick question? It could be. Let's look at AC and DC and see what's up. We'll start with DC. DC is direct current. The voltage of "regular" DC is a fixed value. Like in a car, the battery is about 12 volts. (It's actually a bit higher, but work with me here.) It's a nice, constant 12 volts all the time. The headlights experience a constant 12 volts when they are on. What about AC? Alternating current, or AC, is based on a voltage source that has a changing polarity. For a while it's one way, and then for a while it's the reverse. Also, the voltage isn't constant and then suddenly changing polarity. If we look at the voltage on an AC line, at a certain instant, the voltage is zero. It then rises up over a short time to some maximum value and then decreases to zero again. Then the polarity changes and the voltage goes to some maximum negative value before returning to zero. We usually think of a sine wave, and that's pretty correct. This is how the voltage is actually generated in a generator. It spins, and the voltage output follows a sine wave. Cool so far? Good. Let's jump. With the AC voltage rising to some maximum value, what is that maximum? And since it rises to the value over a short period of time rather than just jumping straight up there, don't we have to "average out" the voltage over the time it takes for it to get to the maximum? And then "average it out" for the back half of that change as it decreases to zero? Yes, we do. And what we end up with is an "effective" voltage, or a "DC equivalent" voltage. In U.S. houses, the 120 volts AC (again, work with me here) is actually the DC equivalent voltage of the AC sine wave. The sine wave actually has a peak at about 170 volts. We could say that a given sine wave has a peak voltage of 170 volts. Or, since it goes negative as much as it goes positive, the total voltage change from the positive peak to the negative peak is twice the peak voltage, or 340 volts peak to peak. But we like to use the "average" or (mathematically) the root mean square voltage, which is the DC equivalent voltage to measure AC. So if an incandescent reading lamp on an end table in a house is plugged into a 120 volt wall outlet, it will have the same brightness as if the lamp was hooked up to a 120 volt DC battery. The effective voltages will be the same because the AC voltage is actually based on the DC equivalent voltage.
Why is there a difference between dc pass through and bidirectional with coaxial splitters?
A DC pass through will pass a DC voltage in only one direction. Bidirectional will let a DC voltage travel both directions.
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.
What is the term used to identify an av voltage that would cause the same heating in a resitor as a corresponding value of dc voltage'?
the RMS value of ac voltage is equivalent in power to the exact same DC voltage. This will cause the same amount of heating in a resistor.
When you stepup ac voltage the current drops.What will happen with CURRENT if DC is stepped up?
WHEN YOU STEP UP THE VOLTAGE AND THE LOAD IS THE SAME MORE CURRENT WILL FLOW NOT LESS. AND THAT WILL HOLD TRUE FOR DC AS WELL. IF THE LOAD REMAINS THE SAME AND YOU INCREASE THE CURRENT AC OR DC THE VOLTAGE WILL INCREASE
Will lower DC voltage or higher DC voltage burn out switch contacts faster if current and resistance stay the same?
if there is resistance in the contact surface , it would heat up more with higher voltage .
What are 4 types of DC voltage?
There is only 1 type of DC voltage, and that is direct current. In order to better answer your question, you need to be more specific.
How do you calculate the voltage average 240v from a 325v 50Hz sine wave peak?
If there is no DC bias, the average is zero. If there is a DC bias, the average is the DC bias. Somehow, I don't think that's what you are actually looking for, though. Please rephrase your question. Perhaps you mean how do you convert between RMS/peak/peak to peak voltage???What_is_the_conversion_for_rms_voltage_to_peak_to_peak_voltage
How you can change a constant DC voltage to a variable DC voltage?
By installing the varialble resistor in the circuit,the constant dc voltage would change .

How do you convert 23 voltage DC to 230 Voltage AC?
What will happen when a dc source is used in front of a diode in half wave rectifier?
If the DC source biases the diode off, then the output will be zero. If it biases the diode on, then the output will be DC, with the voltage being nearly the same as the input voltage.
What is meant by DC-DC luo converter?
luo converter is a new technique adopted for dc to dc voltage lifting(dc voltage boosting)...
What is DC to DC conversion?
A DC to DC converter is a type of switching regulated powersupply whose input is a DC voltage, it then switches that rapidly to make AC, which is applied to the primary of a transformer, the transformer then either steps up or down the voltage as desired, the AC from the secondary is then rectified and filtered to provide the output DC voltage. Regulation circuitry measures the output DC voltage, continuously adjusting the switching circuits on the input to keep the output constant.Most switching regulated powersupplies are DC to DC converters with a simple unregulated rectifier and filter to convert the input AC to DC. Usually it is called a powersupply when it provides more than one output DC voltage or if its input is AC; whereas it is called a converter only if it provides just one output DC voltage and its input is DC. But most of the circuitry is the same in both cases.
