Do the transistors obey Ohms law

Ohms law "V= RI" is the " F=ma or Newton's Law" of Electricity. It gives the quantitative relationship between the three important concepts of electricity, V=Voltage, I= Current and R= Resistance. Answer Ohm's Law is not really important at all, as it is not universal and applies to very few conductors and, then, only under very strict conditions. For a circuit to obey Ohm's Law, its ratio of voltage to current must remain constant for variations in voltage, and this is rarely the case! Most conductors, and most electric devices such as diodes, etc., simply do not obey Ohm's Law. In fact, some engineers and scientists would argue that Ohm's 'Law' should not be a law at all as it applies in so few circumstances. The problem is that many people, including many electricians, mistakenly think that Ohm's Law is represented by an equation that tells us the resistance is voltage divided by current whereas, in fact, this equation is derived from the definition of the ohm, and NOT from Ohm's Law.
