Which Two electrical quantities are measured in volts?
AC and DC
What can you power with 10 volts?
Be it AC or DC any device who's nameplate reads 10 volts.
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.
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.
Why does a 36 volt dc motor only run on 12 volts?
Motors work on both DC and AC. It depends on their design.
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 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.

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
Which Two electrical quantities are measured in volts?
AC and DC
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.
