What it calculates
The “Transistor Bias” calculator computes Collector current Ic in mA from 7 parameters: supply voltage vcc (V), r1 (upper divider resistor) (kΩ), r2 (lower divider resistor) (kΩ), rc (collector) (kΩ), re (emitter) (kΩ), current gain β, voltage vbe (V).
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters Supply voltage Vcc = 12 V, R1 (upper divider resistor) = 47 kΩ, R2 (lower divider resistor) = 10 kΩ, Rc (collector) = 2.2 kΩ, Re (emitter) = 1 kΩ, Current gain β = 100, Voltage Vbe = 0.7 V the result is 1.29 mA.
How to use
