Calculate the current you need to pass through the transistor when its on that is your collector current. The base current ib of a transistor is a crucial current of a bipolar junction transistorwithout this base current the transistor cant turn on. Transistor Base Resistor Calculator How Can You Calculate Base Voltage Of A Transistor When Electronics Club Transistor Circuits Functional Model Here is a calculator for transistor base resistor values. Calculating base resistor transistor . Note the lack of a bias resistor at the base in that circuit. Its important that you read the following. If the transistor is bc547 what should be base resistor. To calculate a suitable value of the base resistor rb we start by calculating the saturation current at the collector i csatthen using a gain of 10 we use the gain formula to find the required saturat...
