Deviation of resistor and capacitor components
Johnson–Nyquist noise
However, the combination of a resistor and a capacitor (an RC circuit, a common low-pass filter) has what is called kTC noise. The noise bandwidth of an RC circuit is Δ f = 1 4 R C . {displaystyle Delta f{=}{tfrac {1}{4RC}}.} [ 7 ] When this is substituted into the thermal noise equation, the result has an unusually simple form as the value ...

Discharging. Discharging a capacitor through a resistor proceeds in a similar fashion, as illustrates. Initially, the current is I 0 =V 0 /R, driven by the initial voltage V 0 on the capacitor. As the voltage decreases, the current and hence the rate of discharge decreases, implying another exponential formula for V.
