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 )

-- 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.
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.

The cost of an RC Plane depends entirely on quality of it, the cheapest ones are often found in the $100-$200 range, with sales putting them as low as $50-80 from time to time.
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'.
sounds same to me.maybe you meant advantage of LC filter over RC filter
A: i am afraid that will take total redesign.
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.
A: A spike noise can be handled with a snubber of the proper value. Snubber is to be put across the source at the spike to absorb the energy usually an RC will suffice.
RC circuits can be used to filter a signal by blocking certain frequencies and passing others.
The clear cover value for the RC water tank is approximately $50.
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.
Its function is to filter the voltage across the load.
You do NOT need a special tool to remove the filter http://www.youtube.com/watch?v=0FqLKzINM6s -RC-
Wouldn't it be as simple as putting an RC filter on the select line?
time delay will be 1/RC x 5 where R = value of resistor in ohms C= capacitance in Farads time delay will be 1/RC x 5 where R = value of resistor in ohms C= capacitance in Farads time delay will be 1/RC x 5 where R = value of resistor in ohms C= capacitance in Farads
K stands fr gain....KRC STANDS FR GAIN OF RC FILTER
