What is the Effect of collector resistance in emitter follower circuit?

Colector resistance in an emitter follower circuit serves to place a limit on how much current can be supplied by the transistor. Often, the resistor is sized so that a short circuit in the load does not cause the transistor to fail.


What was the major effect of replacing the two diodes with resistors?

As I have no information on the circuit I can make no valid predictions as to the effect of replacing diodes with resistors. However I assume the effect(s) will resemble that of having very defective diodes in the circuit.

How a transistor use as a switch?

A transistor (bipolar junction transistor BJT) will only conduct in ONE DIRECTION. And the voltage drop is not Ohmic - it is *NOT* strictly related to current flow. If you're referring to a Field-Effect Transitor (JFET, IGFET, MOSFET, etc), then the device may be able to be used in a bidirectional circuit. But the question stated "transistor", which is understood to be a BJT.

Why is MOSFET called IGFET?

MOSFET is Metal Oxide Semiconductor Field Effect Transistor. IGFET Insulated Gate Field Effect Transistor. But these expressions are practically synonyms.

Why does a phase shift occur in a ce transistor?

In any transistor circuit , there is a phase shift. It takes a finite time for the controlling signal, usually on the base connection, to have an effect on the circuit and cause a change to the output. The shape of the signal remains but it is shifted in time (phase). The difference varies by configuration. It can be as much as180 degrees if the circuit is inverting the signal. The addition of passive components add to the shift.


Where was the transistor created?

The transistor was created by researchers at the university of Geneva. "The first patent for a field-effect transistor principle was filed in Canada... 1925. In 1934 German physicist Dr. Oskar Heil patented another field-effect transistor."
