Base Amplifier Current Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Base Current - (Measured in Ampere) - Base Current is a crucial current of bipolar junction transistor. Without the base current, the transistor cannot turn on.
Collector Current - (Measured in Ampere) - Collector Current is an amplified output current of a bipolar junction transistor.
Current Gain - Current Gain is the ratio of output current to the input current of an amplifier is defined as current gain.

STEP 1: Convert Input(s) to Base Unit

Collector Current: 100 Ampere --> 100 Ampere No Conversion Required
