interesting source functions – unit impulse function
(t) and unit step function u(t). These
functions are extremely important in Circuit Analysis.
3.1 THE RESISTOR
The physical basis for the two-terminal element, called resistor, was dealt in detail in
Chap. 1. We revise briefly.
The source of e.m.f. in a circuit sets up charge distributions at the terminals of all the
two-terminal elements connected in the circuit. This charge distribution at the terminals of
a resistor sets up an electric field inside the conducting material in the resistor. The mobile
electrons get accelerated by this electric field and move. But, their motion is impeded by
frequent ...
