What is the phase shift between voltage and current when an capacitance is connected to the circuit?

The amount of phase shift depends on the resistance that is also present in the system. In an ideal situation, the phase shift would be +90 degrees, but that would require a voltage source with zero resistance, conductors with zero resistance, and an ideal capacitor that exhibited only 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 difference between capacitive reactance and capacitance?
Capacitance is a physical characteristic of a pair of conductors, dependent upon the distance between them, the opposing cross-sectional areas of those conductors, and the nature of the dielectric between them, and is measured in farads.Capacitive reactance is the opposition to the flow of current of a circuit, determined by that circuit's capacitance and the frequency of the a.c. supply applied to that circuit, and is measured in ohms.
What is the change in current when frequency changes from 8 khz to 400hz?
That depends on the circuit. For a pure resistive circuit (no inductance and capacitance), the frequency will have no effect on the current.
What is the relationship between resistance and current in a resistive circuit?
:) It's connected together
Capacitance is the property of an electrical circuit that?
A capacitor resists a change in voltage, proportional to current, and inversely proportional to capacitance. The equation of a capacitor is dv/dt = i/c.
What does not limit current flow in a circuit - capacitance - high conductor resistance or longer conductor?
Of the three choices, capacitance does not limit current flow in an AC circuit.
The phase angle between voltage and current in an a c circuit through a pure capacitance is?
90 DEGREE

What is used to measure the current in a circuit and how is it connected?
To measure the current in the circuit an ammeter is used and it is connected in series
Does capacitance exists between two current carrying conductors?
Capacitance exists between any two conductors, current carrying or not.

a 30 pf capacitor is connected into a 240v, 60 hz circuit. what is the current flow into the circuit
Capacitance is the property of an electrical circuit that?
A capacitor resists a change in voltage, proportional to current, and inversely proportional to capacitance. The equation of a capacitor is dv/dt = i/c.
What is the iffrence between a series circuit and parallel circuit?
Series circuit: elements are connected one after the other; the current (the electrons, or other charge carriers) has to pass through each of the elements in turn. Parallel circuit: elements are connected in such a way that part of the current will pass through one circuit element, part through the other.
How is a series circuit different to a parell circuit?
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
