Q1:

Thermal run away of a transistor occurs when

A heat dissipation from transistor is excessive

B transistor joints melt due to high temperature

C there is excessive leakage current due to temperature rise

D none of the above

ANS:B - transistor joints melt due to high temperature

1mv is the input to generator (ie open circuit voltage ) then 1mv * 600/(600+400) = .4.
