Sorry I just noticed you want this for a DC voltage line, For this you would need to design in a flip-flop circuit to the circuit at the link above. If you need this, just email me and I can do this for you.... at a cost of course ;-)
AC is alternating current like in your house. DC is direct current like in your car.
OneDirection = direct current OppositeDirection = alternating current Source=physics lessons and gives exams :)
These things use dc: batteries provide direct current, so anything run by batteries; electrolysis, used for electroplating, aluminium manufacture and the production of sodium hydroxide.
Alternating current direct current 1973
The bands name comes from the term automatic current- direct current.
you need to test it with a multi meter, set on the right settings. if you knew the voltage you could get an appropriate light bulb to suit the voltage and put that across the wire to test if there is current.
This is known as DC. Direct Current.
Direct current (DC) is nothing but an electric current flowing only in one direction.
A series circuit is where there is only one path for the current. As a result, and as a direct consequence of Kirchoff's current law, the current at every point in a series circuit is the same. The two bulbs have the same current flowing through them.
Capacitors resist a change in voltage, proportional to current and inversely proportional to capacitance. In a DC circuit, the voltage is not changing. Therefore, after equilibrium is reached, there is no current flowing through the capacitor.
The electric current from a battery is the flow of charged particles, typically electrons, through a circuit. The current is measured in Amperes (A) and represents the rate at which charged particles move through the circuit. It is essential for powering electronic devices and creating electrical circuits.
Direct current is a flow of electricity which only goes one way. Batteries, for example, produce direct current, so the current must flow all the way through a circuit and back into the battery to work. Alternating current is what comes out of a wall outlet, and it alternates in both directions, with current flowing in and out of the outlet.
(a) A current flowing in one direction only; -- distinguished from alternating current. When steady and not pulsating a direct current is often called a continuous current. (b) A direct induced current, or momentary current of the same direction as the inducing current, produced by stopping or removing the latter; also, a similar current produced by removal of a magnet.
its called a direct current aka DC
When a direct current (DC) flows through a conductor, it generates a magnetic field around the conductor. This phenomenon is described by Ampere's law, which states that a magnetic field is produced around a current-carrying conductor. The strength of the magnetic field is directly proportional to the current flowing through the conductor.
Alternating Current which reverses its direction regularly at certain intervals Direct Current flowing continuously in one direction only
Direct Current (DC) is an electric current flowing in one direction only.For the source and more detailed information concerning this subject, click on the related links section indicated below.
