Vbe

Vce

hFE

First you must check the datasheet of the transistor in question and identify the values Vbe, Vce, and hFE. These values are responsible for enabling transistor saturation. Here the example numbers shown are for the BJT BC548.

RL

Vcc

Vi

The load resistance RL is indicated in ohms, the supply voltage input is indicated as Vcc, and the input trigger voltage is indicated as Vi.
