Hi pass says it passes higher frequency signals and blocks lower pass signals. This isn't typically a hard cutoff point but the lower frequency signals get attenuated over a frequency range. The R stands for resistance and C for capacitance such that these components are used to create the pass band for the circuit.

Low-pass filter phase shift?
ONE low pass(RC) circuit gives 60 degrees phase shift
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.
What happens to the total impedance of a series RC ciRCuit as the frequency is increased?
when the frequency is increased the total impedance of a series RC circuit is decrease.
What type of circuit is it when capacitors are combined with resistors?
RC Circuit
What is the difference between LC and RC filters?
LC means coil capacitance circuit RC means resistance capacitance circuit
Why high pass circuit is called as an Differentiator?
That is its function. An RC low pass circuit is an integrator.
Explain when step input is given to high pass RC circuit what will be output?
exponential
How the magnitude of voltage and current will behave if you double the RC-ciRCuit input frequency?
If you double the the RC circuit input frequence, the magnitude of voltage and current depends on whether or not the RC circuit is configured low-pass or high-pass, and on whether or not the original frquency is close to the knee frequency (the -3db point). The question has insufficient information to be answered completely.
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 can you change a high-pass RC filter to a low-pass RC filter?
A: i am afraid that will take total redesign.
What is working of low pass RC circuit?
Its function is to filter the voltage across the load.
Low-pass filter phase shift?
ONE low pass(RC) circuit gives 60 degrees phase shift
Why RC oscillators are not suitable for high frequency generation?
Because an RC oscillator is affected by stray capacitance in the active components in the circuit. HF oscillators use an LC tuned circuit to define the frequency.
Why low pass RC circuit can not alter the shape of the sinusoidal signal?
because it is an alternating wave and it has no dc value on it.In RC circuit the capacitor blocks only dc values and it allows all ac values so the wave shape is preserved
