Enter your own electrical network and the applet will draw the impedance graph! See here for instructions how to enter an electrical network.

Instructions how to enter an electrical network.

This impedance calculator can only calculate the impedance graph for passive networks. This means that the only components you can use are:

A value can be entered in scientific notation. For example 1E3 or 3E-6. The decimal dot is not supported so a value of 1.25 should be entered as 125E-2.

With the three components R, C and L you can create electrical networks by connecting them in parallel (entered as // or /) or in series (entered as +). // has precedence over +. You can use ( and ) to specify the precedence.

For example: The following electrical network:
Example of an electrical network
Should be entered as: (R(100)+L(3E-4))//(R(100)+C(1E-6))
