Galvano Demonstration or Voltmeter or Ammeter..

Body: A Bakelite molded ring 170 mm dia mounted with three sets  of winding either 2, 50 & 500 turns or 2,5 & 50 turns ,connected to brass terminalsCoil: the number of turns is clearly marked between the terminalsBase: the ring is mounted on a round Bakelite base which  rotates on an aluminum tripod base fitted with three brass le..

* It has large round rigid die cast body* this is preferred over Bajaj type because of its larger time period approx 10-12 sec. * While find the time period of Galvanometer coil, its circuit must be kept open.* the scale of Lamp & Scale app. should be set up at a distance of one meter from its mirror...

Body    : The moving coil system is housed in aluminum case with removable front sliding cover with three leveling screws                A rectangular coil is suspended with the help of a fine phosphor bronze  suspension wire and moves in a stro..

Galvanometer D'arsonal..

Exp: to study the variation of Magnetic Field with Distance It consists of equal co-axial coils (parallel to each other) separated by a distance equal to the radius of the coils. A compass is pivoted on the Brass cup at the mid way between them & in the same direction...
