d.c. transients

Publisher Summary

This chapter discusses the direct current (d.c.) transients. When a direct current (d.c.) voltage is applied to a capacitor C, and resistor R connected in series, there is a short period of time immediately after the voltage is connected, during which the current flowing in the circuit and the voltages across C and R are changing. These changing values are called transients. There are two main methods of drawing transient curves graphically, namely, the tangent method and the initial slope and three point method. For a growth curve, the value of a transient at a time equal to one time constant is 0.632 of its steady state value—usually taken as 63% of the steady state value. At a time equal to two and ...
