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 ;-)

∙ 11y agoBecause most household cords have both positive and negative wires inside them, any forces such as flux and magnetic fields generated by the electricity tend to cancel each other out so playing games like looking for magnetic fields or measuring flux generally fail. If you can separate the wires from each other it will be easier to succeed using these methods if you have sensitive instruments. If a cord has a heavy load it may be warm. If a spark is generated when plugging or unplugging a cord it means the cable has a load on it. For example, if you plug or unplug a hairdryer while it is turned on you will see or hear a small spark as the electricity jumps across the circuit. If the hair dryer is turned off, there will be no spark.

when electric current is flowing there is a magnetic field surrounding it. you can possibly get a magnet and you can maybe feel a magnetic pull. i think this is what's happening... i'm not 100% sure

What does the letters acdc stand for in the rock band?
AC is alternating current like in your house. DC is direct current like in your car.
What current flows in One Direction?
OneDirection = direct current OppositeDirection = alternating current Source=physics lessons and gives exams :)
What is direct current used for?
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.
What does ACDC Stan for?
The bands name comes from the term automatic current- direct current.
When did acdc get together and does acdc stand for anything?
Alternating current direct current 1973
Direct current an electric current flowing in one direction only?
This is known as DC. Direct Current.
What is direct current stand for?
Direct current (DC) is nothing but an electric current flowing only in one direction.
What is current flowing in One Direction?
There is two types of current. Direct current and alternant current. The one running in only one direction is Direct current.
How can you detect a direct current flowing thugh a wire?
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.
What is a direct currnet?
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 W bulb and a W bulb are connected in series in a circuit Which bulb has the greater current flowing in it?
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.
Is a house direct or alternating current?
The current flowing in a normal household lighting electric bulb is AC. DC systems are just a fraction of 1% in ordinary household systems.The current flowing in a flashlight bulb is Direct Current (DC) if the flashlight runs on batteries.
Why is it capacitance does not affect current in a Direct Current circuit?
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.
What is the electric current from a battery?
A direct current is obtained from a connection to a battery.
What is a currnet?
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.
Realation of current with power and time?
There is no direct relation of electric current and power. In order to knowhow much power (or energy) the current gives up, you must know what thecurrent is flowing through.The easiest way to describe anything through which the current is flowing isto measure and state its electrical resistance.Once you know the resistance through which the current is flowing . . .Power delivered by the current = (magnitude of the current, amperes)2 x (resistance of the path, ohms)The power is delivered continuously. Its unit is watts.Each watt of power means 1 joule of energy every second.
What is the definition of direct current?
(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.
