The diagram below are two simple electron circuit label A and B. Study them carefully and answer the
question that follows

1) Name each of the component I, II, III, IV
2) State the mode of connection in the circuit
Labeled
A&B
3) state the observation that would be made when the circuit labelled
A&B is closed
4)Give one reason each for your answer one question 3

Plot schematically the tensile stress versus strain curves for a typical thermoplastic material at a temperature below its glass transition temperature (tg and at a temperature above its tg, respectively. do the same for a typical thermosetting material. list in a table any differences or similarities between the two materials at t> tg and t < tg, respectively, and relate them to the structures of the two types of polymers
