Voltage Divider Bias Resistors Calculator
Use this page to estimate the bias resistors of a voltage divider circuit.
Calculation includes the effect of germanium transistors leakage current in mA, iL text field. For silicon transistors use iL = 0.
Values are very sensitive to small changes in hFE and iL, therefore precise readings are required to estimate variables with reasonable accuracy.
R2 can be made infinity by making it a large number.
