- Purpose of use
- calculating resistance of a fruit
- Comment/Request
- I believe that the fruit can be represented by an RC circuit, and I would like to make the measurement in a known frequency. I can measure the ''Z'' and the phase shift in degrees.

I would like to extract the ''R'' and ''C''.

Clarification: Having: ''F'', ''Z'', ''Phase'', need to extract: ''R'' and ''C''.

- Purpose of use
- designing feedback loops in regulated power supplies
- Comment/Request
- The negative sign for the phase is correct as the definition is "current delay from voltage". Since the current leads the voltage in this circuit, the "delay" is negative.

- Purpose of use
- Verifying circuit analysis of R & C in parallel.
- Comment/Request
- Would be nice if it supplied the complex impedance in rectangular rather than polar form. But the equation is enough for me to do that I suppose.

- Purpose of use
- Got stuck on a problem
- Comment/Request
- In a parallel rc circuit it is a positive phase angle. This showed a negative.
