ovable coil, or volt coil, is wound with a few turns of very fine wire and connected inseries with a high resist-ance, the terminals be-ing brought out to in-dependent bindingposts, as shown at thetop of the Weston in-strument. A pushbutton switch is in-serted in the volt coilcircuit. The mov-able… … m PRACTICAL ELECTRICITY. The current in the volTcoil will vary as the potential dif-ference between its terminals and the current through theampere coil will vary as the current in the circuit in whichit is inserted. The force acting upon the movable coil, or theforce required to bring it to zero,…
