In a few sentences (1-3), answer the following: a) How does output relate to input for RC circuits when the input is a single frequency sinusoid? b) Given sinusoidal inputs what other component foes a capacitor behave like? How might this be helpful for solving resistor/capacitor type circuits that have sinusoidal inputs as well? c) When should you use impedance (/in what situations could you/) to solve RC circuits and in what situations do you calculate transient response?

Please answer the question below: "Compare the equations for the following factors that define the rate of flow: Diffusion flux, Heat flux, and Electrical current density." (not too sure what the question is completely asking for, but if you can please just provide the eq's, background of each one and how they relate/don't relate to one another I'd really appreciate it and will give you a thumbs up!)
