DESCRIPTION

Exhibit 934 is a variac, or variable transformer, to control an alternating current voltage.

The device consists of a coil wound on a toroidal iron core and excited by the input voltage. There is a carbon cursor rotatable by the external knob and in contact with the coil that permits a variable fraction of the input voltage to appear at the output.
