Purpose of use
fan regulator
Comment/Request
give me circuit diagram with component rating of capacitor base fan regulator

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
Very handy for quickly performing calculations over a broad range of subjects. Thank you for making it available.

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
Checking own calculations before teaching

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.

It's late and I can't do math right now.
Comment/Request
Good explanation of calculations.

Purpose of use
I like to take a circuit and find out in detail how it works, and this website does just that helping me understand the operation of the circuit.

Thanks
