Digital devices deal with logic levels, you need a steady (DC) voltage to represent a 1 and another steady voltage to represent a 0. Power is used each time a level changes.
AC is constantly changing, and is defined by a peak voltage and a frequency, so a single voltage reading is meaningless. For example a house outlet could be 140V one time then -30V, etc (120V outlet swings between -170V and 170V)

Can you convert a DC motor to run on AC?
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
How do you conver ac power into pulsating DC What devices you need?
rectifier circuit convert ac to dc signal
How do you differentiat dc motior and ac motor physicaly?
if you power an ac motor with dc or a dc motor with ac you will likely start smelling smoke and the motor will be damaged. If the motor is marked "3-phase", "shaded pole", or "induction" it is an ac motor! BTW, there are ac/dc motors that will run on both, they are wound very much like dc motors but a bit differently.
How are robots different to computers?
funny looking face and no legs
What do the dogsled dogs need?
they need these thing that are on there feet and there called booties. they need the snow to run in. they will need a sled to run of course. they need the chains that go on the sled.
What are the requirements of dc motor?
You need suitable DC power source to run it.
How do Computers run?
Computers run off of power. You will need to plug your computer into an outlet and turn it on.
Do all electrical home appliances use a DC supply and why?
Not all home applications are run exclusively by a dc current, ex: light bulbs Although some applications involve a dc current requirement such as battery chargers, computers and radios.
Can TV be run by DC supply?
no... run tv with dc supply
Can one dc motor run the wheel and crank?
yes ,but it need good function geat system and high watt dc motors
What is the Need of dc motor?
DC motors are not common in industry. However traction motors are one such main DC motor application. There are many tools, toys, drones, which use DC motors run by batteries.
What computers can play dc universe?
All you need to do is go on canyourunit.com and it will tell you system requirements of any game out there. good luck
Can you run power windows on a DC current?
Power windows ONLY run on DC current.
What does a DC to DC converter do?
A DC to DC converter is a power converter that converts a current from one voltage unit to another. Popular uses of a DC to DC converter are cellular phones and laptop computers.
I need to know it their is some type of computer or circuit board to pulse a 12 volt DC current The amount of pulses per minute needs to be adjustable also need?
One way of doing this, although maybe not the easiest, would be to use a so-called embedded computer. There are a number of embedded computers made for hobbyists that are relatively inexpensive and easy to use. Although these computers cannot themselves control 12 volts DC, they can control transistors or relays which in turn can turn 12 volt DC on and off. Two examples of these computers are the Arduino and the computers made by Parallax.
Is their any other difference between ac and dc current?
Yes, there is. AC = Alternating Current, the direction of the current alternates, thus the name. DC = Direct Current. Things like computers need DC (they use a AC to DC converter inside the power supply to convert it) Hope that helps a bit.
Do radios run on batteries?
Some can be, and some are run by electricity. They all run on electricity. But some run on DC battery voltage and some run on AC household voltage. Some can even run on DC or AC voltage. All automobile radios run on DC battery voltage.
