- A 60 cycle tuned circuit. (parallel)
Three condensers 8.8 mf 9.78 m.f. 9.49 mf. and an air cove reactance with a variable reactance (mutual) i.e. variable coupling, connected in paralel.
Test of circuit containing condensers.

Inductive circuit

1.33-1.13= .20 amperes of leading current needed. This requires a condenser of a capacity [equation]
A total of 31.75 mf is needed for resonance to occur at 60 cycles. Three condensers were obtained (1.95 + 2.28 + .50) m.f. bringing the total to 31.8 mf. The .5 mf condenser burnt out so only 31.3 mf remains.
The parallel circuit was now connected up and found to be ok.
