STEP 0: Pre-Calculation Summary

Formula Used

Current Gain = Collector Current/Base Current
A_i = I_c/I_b
This formula uses 3 Variables

Variables Used

Current Gain - Current Gain is a measure of how much the collector current of a transistor amplifies the base current.
Collector Current - (Measured in Ampere) - Collector Current is the current that flows through the collector terminal of the transistor.
Base Current - (Measured in Ampere) - Base Current is the current that flows into the base terminal of the transistor.

STEP 1: Convert Input(s) to Base Unit

Collector Current: 0.27 Ampere --> 0.27 Ampere No Conversion Required

How does current flow in a transistor?

Current freely flows from collector to emitter. Cut-off -- The transistor acts like an open circuit. No current flows from collector to emitter. Active -- The current from collector to emitter is proportional to the current flowing into the base.

How to Calculate Common Emitter Current Gain?
