The equivalent impedance of a resistor and capacitor in parallel is calculated using the formula Z 1 / (1/R 1/Xc), where Z is the total impedance, R is the resistance of the resistor, and Xc is the reactance of the capacitor. This formula takes into account the combined effects of resistance and capacitance in the circuit.

What is the total impedance of a circuit with a capacitor in parallel with a resistor?
The total impedance of a circuit with a capacitor in parallel with a resistor is calculated using the formula Z 1 / (1/R 1/Xc), where Z is the total impedance, R is the resistance of the resistor, and Xc is the reactance of the capacitor. This formula takes into account the combined effects of resistance and reactance in the circuit.
How does the behavior of a circuit change when a capacitor and resistor are connected in parallel?
When a capacitor and resistor are connected in parallel in a circuit, the behavior changes in that the capacitor stores and releases electrical energy while the resistor controls the flow of current. This combination can affect the overall impedance and time constant of the circuit, leading to changes in the voltage and current characteristics.
How to add a capacitor and resistor in parallel?
To add a capacitor and resistor in parallel, simply connect one terminal of the capacitor to one terminal of the resistor, and then connect the other terminal of the capacitor to the other terminal of the resistor. This creates a parallel circuit where both components share the same voltage.
How can a capacitor be charged without using a resistor?
A capacitor can be charged without using a resistor by connecting it directly to a power source, such as a battery, which provides a constant voltage. This allows the capacitor to store electrical energy without the need for a resistor to limit the flow of current.
What happens to the resistance when the frequency is doubled?
When the frequency is doubled, the resistance of a circuit remains unchanged. Resistance in a circuit is independent of frequency and is determined by the material and physical dimensions of the resistor.

Does the impedance of a parallel RLC circuit equal to the value of the resistor?
No. You have to consider the inductor and the capacitor. Impedance of RLC circuit is equal to to the Value of Resistor Only AND Only on Resonate frequency. otherwise u have to cnsider resistance inductance and capacitance together in series.
Why capacitor reduce gain of ce amplifier?
Where is this capacitor in the circuit?A capacitor across the emitter bias resistor actually increases the AC gain because it bypasses that resistor, by increasing the ratio of collector impedance to emitter impedance which determines the amplifier voltage gain.A capacitor across the base input resistor actually increases the AC gain because it bypasses that resistor, by decreasing the attenuation of the input signal by the input circuit network.
Lrc parallel circuit?
LRC parallel circuit contains its component in parallel connectio. It contains inductor, resistor and a capacitor. A parallel circuit is a closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit
IN case of lossy capacitor what effect would be on series equivalent resistor?
In case of a lossy capacitor, its series equivalent resistance will be large.
How component size decreases when frequency decreases?
The impedance of a component (inductor or capacitor) will change with frequency - resistor impedances will not. Inductor impedance - j*w*L Capacitor impedance - 1/(j*w*C) L = inductance, C = capacitance, j = i = imaginary number, w = frequency in radians The actual inductance and capacitance does not change with frequency, only the impedance.
A resistor and a capacitor are connected in parallel across a 120 v dc source determine the voltages across the resistor and the capacitor?
Since they're connected in parallel directly across the source, the voltages across both componentsare equal, and are equal to the source, i.e. 120 v DC.
How much voltage does a resistor drop in a circuit with 20 volts 1kHz capacitor at 0.47 milli Farads and a 400 ohm resistor?
The reactance of the capacitor is 0.339 ohms, therefore the total impedance is sqrt(4002+0.3392) = 400.0001 ohms. So the resistor drops very nearly 20 volts, very slightly less.
What is function of emitter bypass capacitor?
A: THE EMITTER resistor sole function is to provide stability if it is by passed by a capacitor then this resistance will change due to frequency since as frequency increases the impedance decreases. The total gain will change accordingly
