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

STEP 1: Convert Input(s) to Base Unit

Collector Current: 0.27 Ampere --> 0.27 Ampere No Conversion Required
Current Gain: 0.9 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_b = I_c/A_i --> 0.27/0.9

Evaluating ... ...

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 Transistor Base Current?

Transistor Base Current calculator uses Base Current = Collector Current/Current Gain to calculate the Base Current, The Transistor Base Current formula is defined as the current that flows into the base terminal of the transistor. It controls the flow of current between the collector and emitter terminals of the transistor. Base Current is denoted by I_b symbol.

How to calculate Transistor Base Current using this online calculator? To use this online calculator for Transistor Base Current, enter Collector Current (I_c) & Current Gain (A_i) and hit the calculate button. Here is how the Transistor Base Current calculation can be explained with given input values -> 0.3 = 0.27/0.9.

FAQ

What is Transistor Base Current?

The Transistor Base Current formula is defined as the current that flows into the base terminal of the transistor. It controls the flow of current between the collector and emitter terminals of the transistor and is represented as I_b = I_c/A_i or Base Current = Collector Current/Current Gain. Collector Current is the current that flows through the collector terminal of the transistor & Current Gain is a measure of how much the collector current of a transistor amplifies the base current.

How to calculate Transistor Base Current?

The Transistor Base Current formula is defined as the current that flows into the base terminal of the transistor. It controls the flow of current between the collector and emitter terminals of the transistor is calculated using Base Current = Collector Current/Current Gain.
