About AC Voltage Detector
An AC voltage detector' is a device that uses electric fields to see if there is an electric current in a desired circuit or wiring system. This can help out an electrician to the fullest safety measures by not going into the wire itself. One can see the expansion of AC volt detectors through the products on amazon.com. Voltage detectors are available due to different preferences such as : size, range (of current its willing to detect), price and maker.

How it works
The AC voltage detector can detect an electric field. Most of the detection can be done by a simple capacitor. A capacitor has two conductors or “plates” that are separated by a non-conductor called a dielectric. If we connect an ac voltage across the two conductors, an ac current will flow as the electrons are alternately attracted or repelled by the voltage on the opposite plate. There’s a complete ac circuit even though there’s is no wires actually in use. The electrical field inside the capacitor, between the two plates, is what completes the ac circuit. It shows this by giving off an audible noise or an l.e.d. light to signify on how strong the electric field is. The stronger the electric field on a wire or object then the stronger the stronger the audible noise on the detector to help guide where the electricity is running at one time. It also gives the electrician a sense of security for when it comes to coming into contact with that part of the circuit.

Use
The AC voltage detector can be used from a wide range of aspects from detecting where the circuit or the electricity failed to travel from a string of Christmas lights to the most complicated wire set to see where a short is. A basic household may want to have one lying around to check the fuses in a car to see if they are working up to standards. You can set it to a range of frequencies that can only detect certain electrical fields; for example it may be able to read off the connection off of a car battery or the connection of a set of Christmas lights onto the next.

Why to obtain a voltage detector
It is a safe and easy way to see where the break in the circuit is instead of having to cut the wire and seeing if the current runs the that section of the circuit. That requires time and not to mention the destruction of that certain part of the circuit. This is a clean and easy way to actually see if the circuit or system needs work at the certain position. The voltage detectors are known for their “no-touch” reputation and have help out many electricians. Not only does it help out electricians but auto-repair men on checking fuses as well as checking the electrical current.

Which voltage detector to use
Some can use the space saving Digi-Key, which is a type of AC voltage detector that can fit in ones pocket and it is known for its small compact size since it is the size of a bulky pen. Some prefer an older model such as the tic tracer which can fit in the palm of ones hand. However electricians from the past prefer to use this tic tracer and others who need space in ones belt may use the Digi-Key version of this AC voltage detector.
