Galvanometer as a DC Multimeter - Wolfram Demonstrations Project

Galvanometer as a DC Multimeter - Wolfram Demonstrations Project: In a DArsonval galvanometer a disk wound with many turns of fine wire can rotate in the field of a permanent magnet its deflection proportional to the current through the wire. A coil spring (not shown) provides a restoring torque to the disk. As part of an appropriate circuit the galvanometer can function as a DC multimeter measuring the voltage current or resistance of a connected circuit;;
