Tliis last term is defined as follows: Imagine an idealosciHator consisting of two small spheres connected by a thinrod. We may consider that the rod possesses inductance butnegligible capacity, and the whole of the capacity is in the the oscillations a certain quantity of electricity may beconsidered to oscillate backwards and fo
