Why RC circuit is preferred over RL circuit in waveshaping?
There is no true advantage of RC circuits over RL circuits, as they perform different functions. RC circuits contain resistors and capacitors, while RL circuits contain resistors and inductors.
What is the effect of capacitor in the output noise?
The capacitor on it's own is of no use, it is always used in an RC or LC configuration normally in audio frequency's the RC is used to filter the noise down to earth where the RC circuit have to resonate at the same frequency as the noise, the lower the frequency the larger the value of the capacitor
What is time constant of capacitor when resistance is zero?
Time constant in an RC filter is resistance times capacitance. With ideal components, if the resistance is zero, then the time constant is zero, not mattter what the capacitance is. In a practical circuit, there is always some resistance in the conductors and in the capacitor so, if the resistance is (close to) zero, the time constant will be (close to) zero.
What is the resonant frequency of a tuned circuit with 70 ohms of resistance and a 45 microfarad capacitor?
tuned circuit consists of resistance and capacitor so this one RC circuit formula to be used f = 1/ 2 pi RC
What is purpose of emmiter bypass capacitor in R-C coupled amplifier?
Emitter bypass capacitor is a capacitor which provide low impedance to AC and high impedance to DC . AC is shunt then only DC appears on RC and volage gain increses.
What is an RC filter for a ripple?
Place a capacitor across the output or load and you have your filter. This assumes that your load is a resistor. The capacitor you use depends on the frequency of the ripple. Lower frequencies require larger capacitors. A resistor may be required to make sure you do not damage any of the electronics either in series with the capacitor or immediately after the power source.
What is a filter and how it eliminates the ripples of pulsating dc voltage?
A: Assuming RC filter the capacitor will charge trough the resistor for time = r x c at the first pulse the capacitor is zero and charges to 63% or tries to if the pulse has at least 5 times the RC time if not it will try to charge to 63% and discharge at the same rate therefore reaching an equilibrium if the pulses are symmetrical
How capacitor filter works?
The flux capacitor, which consisted of a regularly squared compartment with three flashing lights arranged as a "Y", was described by Doc as "what makes time travel possible". The device is the core component of Doc Brown's DeLorean.

What is RC-coupled?
rc coupling is a coupling that involves capacitor aand resistor
What is RC coupling?
rc coupling is a coupling that involves capacitor aand resistor
Why is capacitor leakage a problem in a RC timer circuit?
Because the timing is set by the time constant of a resistor and a capacitor. With R in ohms and C in Farads, the time-constant is RC in seconds. If the capacitor leaks the timing will be wrong.

In a RC coupled amplifierthe coupling capacitor is used for?
yes
What current exists in a capacitor when it is fully charged in an RC circuit?
When a capacitor is fully charged in an RC circuit, it holds a stored electrical charge. This charge creates an electric field between the capacitor plates, with no current flowing through the circuit at that moment.
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.
What happen if you connect capacitor and resistor in parallel in low pass filter?
Only frequencies in the pass band range will be allowed through the circuit. Other frequencies will be attenuated based on the RC values picked.
