App Description

Input parameters: R1 (ohm); R2 (ohm); C (F)

Output parameters: duty cycle (%), high time (s), low time (s), frequency (Hz)

Calculation formula:

\(TH (high time s) = 0.693 * (R1 + R2) * C\)

\(TL (low time s) = 0.693 * R2 * C\)

\(Frequency = 1.44 / ((R1 + R2 + R2) * C\)

\(DCP (duty cycle \%) = (T(h) / (T(h) + T(l))) * 100\)

\(Frequency = 1.44 / ((R1 + R2 + R2) * C\)

\(DCP (duty cycle \%) = (T(h) / (T(h) + T(l))) * 100\)

Usage example

The capacitance is 1, and the resistance is 2, 5:

TH (high time s) = 0.693 * (R1 + R2) * C = 4.851

TL (low time s) = 0.693 * R2 * C = 3.465

Frequency = 1.44 / ((R1 + R2 + R2) * C=0.120

DCP (duty cycle %) = (T(h) / (T(h) + T(l))) * 100=58.333

Precautions

Note: The input parameter C is the capacitance of the Farad, and the input parameter R is the resistance unit of ohmmeter.
