How to measure current clamp meter
A table is actually a current transformer, the jammed wire is the equivalent of a transformer coil
When there is an electric current in the wire, the magnetic flux is generated in the iron core of the table, and then the current is induced in the two coil,
This current is equal to the current of the first coil (i.e. wire current in a coil) multiplied by the number of turns (actually a wire, so it is a turn) turn number two divided by the coil, according to the relationship, can be converted to a (the wire) of the current..
