Both 5 volts DC and 5 volts AC represent the same voltage level of 5 volts. However, the key difference lies in their waveform. DC is a steady voltage that flows in one direction, while AC alternates in direction, changing polarity over time. This difference affects how each type of voltage is used in various electrical applications.
What else can I help you with?
How can you 120 volts AC to 5 volts DC?
By a DC power supply that runs at 230 volts AC. Basically, you need a full wave rectifier (4 diodes) to convert AC into all positive voltage. Then you need capacitors to smooth out the ripple and then various resistors to reduce the voltage.
Which Two electrical quantities are measured in volts?
Voltage and potential difference are measured in volts.
What are the touch voltage for DC and AC limits in Australia?
In Australia, the touch voltage limit for DC is typically set at 25 volts, while for AC it is set at 50 volts. These limits are based on safety standards to protect against electric shock.
Does a computer use AC or dc power?
Both, in a way. Electronic components, including moth components inside the computer, need DC. However, since the power available in homes or offices is AC, a computer is designed to work with this. A computer has a power supply that internally converts AC to DC.
Can you power a 12 volt dc indicator light from a 16 volt ac door bell transformer?
No, the 12 VDC light must have a DC supply and the transformer voltage as well as being 16 volts which is too high, the output is AC.
What is use of rms value?
Because alternating current (AC) voltage varies over time, to the positive and negative, an actual AC voltage measurement will not be the same as a DC voltage measurement. For example: 5 volts DC is 5 volts constantly, viewed over time. The average voltage is 5 volts. 5 volts AC (from zero to peak) is not actually 5 volts constantly, but varies between 5 volts and 0 volts over time. The average voltage will not be 5 volts. Using RMS AC values is designed to make AC and DC measurements equivalent, for example 5 volts DC and 5 volts RMS AC are almost identical.

How do you calculate the ac amps when you have the DC volts DC amps and the ac volts?
the answer is dc volts are rectified from ac volts and the amperage will be the same unless you account for the slight drop from the rectifier. dc volts from a battery have no relationship to ac volts. you can derive ac volts from a dc source using an inverter.
What is an ac voltmeter?
A: It is a regular DC voltmeter but the AC is rectified and the DC component is measured and displayed as AC VOLTS.
The working voltage of a capacaitor is rated in ac or dc volts?
DC
Is a car cigarette lighter socket ac or dc?
12 volts DC
Is a car battery AC or DC volts?
dc - the voltage is a constant 12 volts nominally in a normal car battery.
Change Ac volts to dc volts?
Use a full wave bridge rectifier.
Is New Zealand mains electricity AC or DC?
AC 220/240 volts
Can you charge battery from ac?
No, it must be charged with a battery charger plugged into 120 volts AC which converts it to 12 volts DC.
Is 12 volts dc as powerful as 120 volts ac?
You get power by multiplying the amperes and the voltage. 12V, 10A dc would give the same power as 120V, 1A ac.
Does DC adapter mean the device converts DC to ac or ac to DC?
An AC adapter adapts the device that one wants to power up to the AC line. That means it converts the AC line voltage to something that can be used by the device in question. An AC adapter converts AC to DC. (In contrast, a device that runs off DC and makes AC out of it is called an inverter. An example of an inverter is the device that plugs into a vehicle's cigarette lighter and has an outlet on the other end that will permit someone to plug something like a kitchen blender into it. Great for tailgating! Don't run your vehicle's battery down....) There are times when an AC adapter is the little plug-in-the-wall thingie that converts the AC line voltage to some lesser value of AC. There are a few devices out there (usually older ones) that used their AC adapters to step down the wall voltage (115 volts AC) to 24 volts AC, 18 volts AC, 9 volts AC, or anything like that. Some new sprinkler control timers use an adapter that is an AC -to-AC step down converter. By looking at the information on the adapter, the user can see what the primary voltage is (and it's almost invariably 115 volts AC or 120 volts AC - same, same for this application) and what the secondary voltage is. As stated, the secondary is almost always DC, and if it is, the polarity is almost always indicated as well. That's so a user can tell if that little round connector has positive on the inside and negative on the outside or the other way round. (It makes a lot of difference to the device on which it is used, as one might guess.)
