- 1). Square the angular frequency then multiply it by the inductance and the capacitance. For example, 366 radians per second squared is 133,956. That value multiplied by 2 henrys and 1 micro-farad yields 0.268.
- 2). Subtract the previous result from 1. For example, 1 minus 0.268 yields 0.732.
- 3). Multiply the angular frequency by inductance and the imaginary number j, then divide by the resistance. For example, 366 radians per second times 2 henrys and j, divided by 50,000 ohms, yields j2.68.
- 4). Divide 1 by the sum of the results of step 2 and step 3. In our example, the result is the fraction 1 divided by 0.732 plus j2.68. This is the LRC transfer function for our case. The answer is necessarily complex, because AC voltage is complex.
