The change in output voltage across the load resistor for a transistor

1.	The change in output voltage across the load resistor for a transistor during amplification is_________(a) RL α∆IE(b) RL ∆IE/α(c) RL α^2∆IE(d) RL α^1/2*∆IEI have been asked this question in examination.This question is from The Transistor as an Amplifier topic in division Transistor Characteristics of Electronic Devices & Circuits
Answer» Correct ANSWER is (a) RL α∆IE The best explanation: A SMALL change of voltage ∆Vi between EMITTER and base causes a relatively large emitter CURRENT change ∆IE. We define by the symbol α that fraction of this current change which is collected and PASSES through RL.
