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 will be the impedance of a C-R circuit consisting of a resistance of 20ohm and capacitance 2microfarad when it is connected to direct current?
In a direct current (DC) circuit, a capacitor will eventually charge up and act as an open circuit, meaning it will not allow current to flow after reaching full charge. As a result, the impedance of a resistor-capacitor (C-R) circuit under DC conditions is simply the resistance value. Therefore, the impedance of the given C-R circuit with a resistance of 20 ohms and a capacitance of 2 microfarads is 20 ohms.
What is the relationship between resistance and current in a resistive circuit?
:) It's connected together
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 capacitance and current in an electrical circuit?
The relationship between capacitance and current in an electrical circuit is that capacitance affects the flow of current in the circuit. A higher capacitance means the circuit can store more charge, which can impact the current flowing through the circuit. The current in a circuit with capacitance can change over time as the capacitor charges and discharges.
What is the relationship between current and capacitance in an electrical circuit?
The relationship between current and capacitance in an electrical circuit is that capacitance affects the flow of current in the circuit. Capacitance is a measure of how much charge a capacitor can store, and it influences the rate at which current can flow through the circuit. A higher capacitance can result in a slower flow of current, while a lower capacitance allows for a faster flow of current.
What is the relation between amperage and capacitance?
The relationship between amperage and capacitance is indirect. Capacitance stores and releases electrical energy, affecting the flow of current in a circuit. Higher capacitance can lead to slower changes in current (i.e., lower frequency), while lower capacitance can result in faster changes in current.
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.
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.
The phase angle between voltage and current in an a c circuit through a pure capacitance is?
90 degrees. In an AC circuit with a pure capacitance, the current leads the voltage by 90 degrees. This is because the current in a capacitor is proportional to the rate of change of voltage across it, leading to this phase relationship.

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.
