If there were no resistance and no inductance in the circuit in the 18 TRANSIENT PHENOMENA moment of closing the circuit, an infinite current would exist charging the condenser instantly to the potential difference e0.

CHAPTER I. INTRODUCTION. 1. Whenever in an electric circuit a sudden change of the circuit conditions is produced, a transient term appears in the circuit, that is, at the moment when the change begins, the circuit quantities, as current, voltage, magnetic flux, etc., cor- respond to the circuit conditions existing before the change, but do not, in general, correspond to the circ ...Chapter 10: Instability Of Circuits : The Arc - 27 hit(s)

... s and arc-lighting machinery, the opinion prevailed that theoretical calculations are impossible and only design by trying, based on practical experience, feasible. The first class of imstable phenomena, which was systemat- ically investigated, were the transients, and even today it is ques- tionable whether a systematic theoretical classification and in- vestigation of the conditions of instability in electric circuits is yet feasible. Only a preliminary classification and discussion of such phenomena shall be att ...Chapter 12: Magnetic Saturation And Hysteresis In Alternat Ing-Current Circuits - 26 hit(s)

... lux produced by the current immediately assume their final or permanent values only in case the circuit is closed at that point of the e.m:f. wave at which the permanent current is zero. Closing the circuit at any other point of the e.m.f. wave produces a transient term of current and of magnetic flux. So for instance, if the circuit is closed when the current i should have its negative maximum value - 70, and therefore the magnetic flux and the magnetic flux density also be at their negative maximum value - ^>0 and ...Chapter 7: Distribution Of Alternating-Current Density In Conductor - 23 hit(s)

An approximate determination of this effect for the purpose of deciding whether the unequal current distribution is so small as to be negligible in its effect on the resistance of the conductor, 369 370 TRANSIENT PHENOMENA or whether it is sufficiently large to require calculation and methods of avoiding it, is given in " Alternating-Current Phe- nomena," Chapter XIV, paragraph 133.
