Voltage Gain given Collector Current Solution

STEP 0: Pre-Calculation Summary

Formula Used

Voltage Gain = -(Collector Current/Thermal Voltage)*Collector Resistance
A_v = -(I_c/V_t)*R_c
This formula uses 4 Variables

Variables Used

Voltage Gain - (Measured in Decibel) - Voltage gain is defined as the ratio of the output voltage to the input voltage.
Collector Current - (Measured in Ampere) - Collector current is an amplified output current of a bipolar junction transistor.
Thermal Voltage - (Measured in Volt) - Thermal Voltage is the voltage produced within the p-n junction.
Collector Resistance - (Measured in Ohm) - Collector Resistance (Rc)helps to set the transistor at the "operating point" of the amplifier. The purpose of the emitter resistor Re is to prevent "thermal runaway".

STEP 1: Convert Input(s) to Base Unit

Collector Current: 5 Milliampere --> 0.005 Ampere (Check conversion here)
Thermal Voltage: 4.7 Volt --> 4.7 Volt No Conversion Required
Collector Resistance: 3.75 Kilohm --> 3750 Ohm (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_v = -(I_c/V_t)*R_c --> -(0.005/4.7)*3750

Evaluating ... ...
