WebApr 1, 2024 · in order to calculate tau, you can use the inductor's value divided by the resistor's value. as the resistance (or impedance, in A/C). As R changes value, tau does … WebSep 22, 2024 · DC means that frequency equals = 0, the resistance is infinite, but you need a value for the resistance to use the formula tau = RC. The R in the time constant is not the resistance of the capacitor, but the resistance of a resistor connected to the capacitor.

WebThe RC constant will also have some handy uses in filtering that we'll see later on. Calculating the RC is straight forward -- multiply the capacitance C, in Farads, by the resistance R, in Ohms. Remember to take care of your powers of 10 -- a micro-Farad is 10-6 F, while a pico-Farad is 10-9 F. In the circuits we'll look at, RC constants often ...
