CENCO Tangent Galvanometer

Description
The CENCO Tangent Galvanometer is a vintage piece of scientific equipment that is used to measure electric current that is run through the device. Compared to other tangent galvanometers of the time, this device has removable switches that changes the number of resistors the current runs through. Other galvanometers of the time typically had multiple ports to run the electrical current through that would put the current into a different number of coils. To derive a value for the current ( "I") using the tangent galvanometer, first make sure the compass is pointing towards zero. When the compass is properly aligned, you may run the current through the two, non-numbered ports. The needle of the compass will deflect from zero to an angle that is proportional to the electrical current. Then, use the formula tanθ=B/BH.
