Design an Inverting and non inverting amplifiers choosing
the right values o for R., Ra and vo.
Derive an expression for Region and to
for both amplifiers.

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
