Time constant = R C

C = time constant/R

R = time constant/C

When used as a filter,

Cutoff frequency = 1 / (2 pi) R C

R = 1 / (2 pi) (cutoff frequency) ( C )

C = 1 / (2 pi) (cutoff frequency) ( R )

Why the capacitor time period formula is given as t equals RC?

-- The quantity 'RC' has the physical dimensions of Time. -- If the capacitor is charging through a resistor, then 'RC' is the time it takes to charge up to (1 - 1/e) of the voltage it still has to go to become fully-charged. -- If the capacitor is discharging through a resistor, then 'RC' is the time it takes to discharge to 1/e of its present voltage. -- ' e ' is the base of natural logarithms, approximately 2.71828... -- 'RC' is called the 'time constant' of the resistor/capacitor combination.


How do you solve for one time constant?

You can solve for a one-time constant by using the formula t = RC. Read the math problem you are given carefully to determine what values to plug into the equation.


What mathematical relationship exists between the times and the capacitance?

The mathematical relationship between time (t) and capacitance (C) in the context of a capacitor charging or discharging in an RC (resistor-capacitor) circuit is described by the exponential function. The voltage across the capacitor as it charges is given by V(t) = V₀(1 - e^(-t/RC)), where V₀ is the initial voltage, R is the resistance, and C is the capacitance. The time constant τ (tau) of the circuit is defined as τ = RC, indicating that larger capacitance or resistance results in longer charge and discharge times. Thus, capacitance directly affects the time it takes for a capacitor to charge or discharge to a certain percentage of its maximum voltage.

Is tau a constant?

Yes, (greek letter 'tau') is used to represent the mathmatical constant exactly equal to 2π (2pi). is also a time constant sometimes referred to as the 'RC time constant'.

What happens if capacitance is increased in parallel RC ciRCuit and series RC ciRCuit?

In both cases, the time constant of the RC circuit is increased. If the application is a high- or low-pass circuit, then the filter cutoff frequency is decreased in both cases. If the application is a phase-shift network, then the frequency for a given phase- shift is reduced.

How is the energy dissipated by the resistor in an RC circuit calculated?

The energy dissipated by a resistor in an RC circuit is calculated using the formula: Energy 0.5 C V2, where C is the capacitance of the circuit and V is the voltage across the resistor.


Why does low pass RC circuit filter the voltage?

In a DC power supply, a low-pass RC filter is typically used to "filter the voltage" by reducing or eliminating any remaining ripple. This works because such ripple has frequency components over 0 Hz (ripple is essentially an AC component with an offset), which are suppressed by the low-pass filter.
