Question

State the principle of moving coil galvanometer. Explain briefly how it can be converted into ammeter. Define toroid

Answer 1

the principle of the moving coil galvanometer :-

the moving coil galvanometer is work on the principle that the current provided is directly propotinol to the deflection of the coil

it can be converted to ammeter by connecting shunt resistance in series to the moving coil galvanometer

toroid:-

toroid is the iron ring coiled with n no of turns of insulated copper wire around it
