If turns are added at the coil, L, the current oscillates through the circuitat a lower frequency; but if turns are taken out at L, the frequency of the oscillations in-creases. In a similar manner, increase of capacity at the condenser C will reduce the fre-quency of the oscillations and decrease of capacity will increase the frequency of the oscilla-tions. In a radio transmitter the capacity of the condenser C is a fixed quantity, and there-fore, the frequency of the oscillations is changed by Lhe variable inductance. 89. Electrical Resonance.—The phenomenon of resonance is very strikingin circuits of radio-frequency. In order that the energy of the oscillations flow-ing in one circuit may be transferred most e
