ALCULATION

Following are the equations used in calculation of Model 7606 performance,
along with a sample calculation.

The absolute value of the ratio of the magnetic flux density to the voltage across
the connected load, BVL, is given by equation 11.

The coil resistance, Rc, is found from the length of wire in the coil and the unit
resistance of the wire; or, it can be measured with a low-resistance bridge. The
length of the wire is the product of the average circumference of the winding and
the number of turns. This is shown in equation 12.
