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. The AC voltage detector can fit in ones pocket and its small compact size since it is the size of a bulky pen. This is a clean and easy way to actually see if the circuit has electrical current.
