The following equations are used to calculate the transistor biasing values:
- Base current (Ib) = Collector current (Ic) / Beta (β)
- Base-emitter voltage (Vbe) = Input voltage (Vin) - Base current (Ib) * Base resistor (Rb)
- Collector-emitter voltage (Vce) = Supply voltage (Vcc) - Collector current (Ic) * Collector resistor (Rc)
