AC Network Analysis
Introduction
So far, we have seen that in linear
resistance networks, the unknown network
variables are obtained by solving a linear
set of equations.
We now start to consider linear networks

VISCOSITY
Viscosity: A property that represents the internal resistance of a fluid to
motion or the fluidity.
The viscosity of a fluid is a measure of its resistance to deformation.
Viscosity is due to the internal frictional force that develops between d
Frequency Response
Introduction 1
Frequency response is the ratio of the
phasor of the output of a circuit (for
example, voltage or current of a load)
to the phasor of the source.
