What is resonant cicuit?
An electrical circuit that combines capacitance and inductance in such a way that a periodic electric oscillation will reach maximum amplitude
What is the relationship between resistance and capacitance in a clc circuit?
The relationship between resistance and capacitance in a clc circuit is the capacitive reactance given by XC.
What is a purely resistive circuit?
It does not contain unidirectional outputAnswerA purely resistive circuit is an 'ideal' circuit that contains resistance, but not inductance or capacitance.
Why is it capacitance does not affect current in a Direct Current circuit?
Capacitors resist a change in voltage, proportional to current and inversely proportional to capacitance. In a DC circuit, the voltage is not changing. Therefore, after equilibrium is reached, there is no current flowing through the capacitor.
What is the reciprocal of capacitance?
How funny... Electrical Elastance measured in daraf's
What is capacitance?
Theoretically, Capacitance is defined as the ability of a component or circuit to collect and store energy in the form of an electrical charge. Mathematically, it is defined as the ratio of the change in an electric charge in a system to the corresponding change in its electric potential.
What is meant by capacitor?
A capacitor is an electrical or elctronic semi conductive material which have the ability to store electrical charge and discharge when needed, and also used for timing a circuit and finally used for filtering in a circuit. A capacitor is made up of two plates seperated by die-electric strength or material. Thanks
When they can use a resistor in a circuit?
When the circuit needs the electrical property of resistance, of course.
What is resonant cicuit?

What are applications of schering bridge?
A Schering Bridge is a bridge circuit used for measuring an unknown electrical capacitance and its dissipation factor.
How much capacitance is used in general circuit?
You need to be little more specific to get an accurate answer. Capacitance in which circuit? Thanks.
The property of an electrical device that permits storage of electrically separated charges when potential differences exist between the conductors is called what?
Capacitance.
What is the difference between LC and RC filters?
LC means coil capacitance circuit RC means resistance capacitance circuit
Reciprocal of capacitance?
Electrical Elastance
What is the relationship between resistance and capacitance in a clc circuit?
The relationship between resistance and capacitance in a clc circuit is the capacitive reactance given by XC.
Define capacitance with respect to physical structure and electrical function?
capacitance, in electricity, capability of a body, system, circuit, or device for storing electric charge. Capacitance is expressed as the ratio of stored charge in coulombs to the impressed potential difference in volts. The resulting unit of capacitance is the farad [for Michael Faraday]. In an electric circuit the device designed to store charge is called a capacitor. An ideal capacitor, i.e., one having no resistance or inductance, may be spoken of as a capacitance. When an alternating current flows through a capacitor, the capacitor produces a reactance that resists the current (see impedance). While every element of a circuit has some capacitance, it is a goal of good design to reduce such unwanted or stray capacitance to a minimum.
What is the effect of capacitance in high frequency circuits and how it is getting added?
First, capacitance is the resistance of something to a change in voltage. And capacitance exists anywhere there is a conductor that is insulated from another conductor. With that definition, anything has capacitance. And that's correct. It is also the key to understanding the capacitance in high frequency (radio frequency or RF) circuits. The fact that a circuit had conductive pathways and component leads and such means that there is a lot of little bits of capacitance distributed around the circuit. The capacitance is already there; it isn't "added" later as might be inferred. Normally, this bit of capacitance isn't a problem. But at higher and higher frequencies, it is. Remember that the higher the frequency of an AC signal, the better it goes through a given cap. So at higher and higher frequencies, the distributed capacitance in the circuit "shorts the signal to ground" and takes it out of the circuit. The RF is said to be coupled out of the circuit through the distributed capacitance in that circuit. The higher the frequency a given circuit is asked to deal with, the more signal will be lost to this effect. It's just that simple. Design considerations and proper component selection minimize the distributed capacitance in a circuit.
