this is the description of my project: A practical problem in domestic electrical installation is that during simple renovation of houses. Concealed electrical wiring makes difficult for the house owner to identify a suitable location to nail the wall. Also to estimate amount of current the cable is conducting without actually connecting to any measurement meter is definitely a great helpful for an electrician to plan on additional electrical installation. This project is to design an electronic circuit with a display unit, which will detect electromagnetic wave/any type of radiated wave a power cable might produce, and use for routing detection as well as to estimate the amount of current it is carrying can i use the metal detector approach for this? im a little confused... i really need advice please
