Current Amplifier Gain Solution

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 the ratio of output current to the input current of an amplifier is defined as current gain.
Collector Current - (Measured in Ampere) - Collector Current in a Bipolar Junction Transistor is the current flowing through the collector terminal.
Base Current - (Measured in Ampere) - Base Current in a BJT is the current flowing through the base terminal, which controls the transistor's operation and amplification characteristics.

STEP 1: Convert Input(s) to Base Unit

Collector Current: 100 Ampere --> 100 Ampere No Conversion Required
Base Current: 105.263 Ampere --> 105.263 Ampere No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_i = I_c/I_b --> 100/105.263

Evaluating ... ...

A_i = 0.950001425002137

STEP 3: Convert Result to Output's Unit

0.950001425002137 --> No Conversion Required

FINAL ANSWER

0.950001425002137 ≈ 0.950001 <-- Current Gain

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 Current Amplifier Gain?

Current Amplifier Gain calculator uses Current Gain = Collector Current/Base Current to calculate the Current Gain, The Current Amplifier Gain formula is defined as the symbol Ai and because it is a ratio, it has no units. For example, if the flow of current from the input signal is 1mA and the current flowing through the output terminals is 100mA, then the gain of the given current amplifier would be 100. Current Gain is denoted by A_i symbol.

How to calculate Current Amplifier Gain using this online calculator? To use this online calculator for Current Amplifier Gain, enter Collector Current (I_c) & Base Current (I_b) and hit the calculate button. Here is how the Current Amplifier Gain calculation can be explained with given input values -> 0.950001 = 100/105.263.

FAQ

What is Current Amplifier Gain?

The Current Amplifier Gain formula is defined as the symbol Ai and because it is a ratio, it has no units. For example, if the flow of current from the input signal is 1mA and the current flowing through the output terminals is 100mA, then the gain of the given current amplifier would be 100 and is represented as A_i = I_c/I_b or Current Gain = Collector Current/Base Current. Collector Current in a Bipolar Junction Transistor is the current flowing through the collector terminal & Base Current in a BJT is the current flowing through the base terminal, which controls the transistor's operation and amplification characteristics.
