Step-by-Step Guide to Using the Impedance Calculator

Welcome to the Impedance Calculator. This tool is designed to help you calculate various parameters of an electrical circuit based on the values you enter. Follow the steps below to use the calculator effectively.

Input Fields

  1. Enter Resistance (R)

    In the Resistance (R) in Ohms field, enter the resistance value of the circuit in Ohms. This value is required for the calculation and must be a non-negative number. You can enter values with up to two decimal places.

  2. Enter Inductance (L)

    In the Inductance (L) in Henries field, input the inductance value in Henries. This is also a required field and must be a non-negative number, with the ability to input values down to microHenries.

  3. Enter Capacitance (C)

    Next, provide the capacitance value in the Capacitance (C) in Farads field. The value should be a non-negative number and can be entered to the nanoFarad level of precision.

  4. Enter Frequency (f)

    Finally, in the Frequency (f) in Hertz field, enter the frequency at which the circuit operates. Ensure this is a positive number and you can specify it up to two decimal places.

Result Fields

After entering all the required data, the calculator will compute the following:

  • Inductive Reactance (XL): The reactance due to inductance, calculated as (2 times pi times text{frequency} times text{inductance}). The result is presented in Ohms to two decimal places.
  • Capacitive Reactance (XC): The reactance due to capacitance, calculated by the formula (1 / (2 times pi times text{frequency} times text{capacitance})). This is also displayed in Ohms to two decimal places.
  • Net Reactance (X): This is the difference between the inductive and capacitive reactances. It is shown as a two-decimal-point value in Ohms.
  • Impedance (Z): Using the formula (sqrt{text{resistance}^2 + text{reactance}^2}), the total impedance of the circuit is calculated. This value is also expressed in Ohms with two decimal precision.
  • Phase Angle (φ): The calculator determines the phase angle using (text{atan2}(text{reactance}, text{resistance}) times 180 / pi). The result is presented in degrees.

By following these steps and entering accurate values, you will be able to utilize the Impedance Calculator efficiently to obtain key electrical parameters of your circuit.
