Enter your own electrical network and the applet will draw the impedance graph! See

## 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:

- Resistor. Entered as
`R(`*value*)

.
- Capacitor. Entered as
`C(`*value*)

.
- Coil. Entered as
`L(`*value*)

.

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:

Should be entered as: `(R(100)+L(3E-4))//(R(100)+C(1E-6))`
