What else can I help you with?
The opposition to the flow of electrical current?
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
Total opposition to current flow in an AC circuit?
I oppose alternating current. Direct is the only way for me. That is 1 in opposition.
Impedience of electric circuit?
The impedance of an electric circuit is the measure of the opposition presented by a circuit when the current and voltage is applied.
When an alternating voltage is applied to purely resistive circuit what happens?
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
Impedance of electric circuit?
The impedance of electric circuit refers to the measure of the opposition that a circuit presents to a current when a voltage is applied.

Impedience of electric circuit?
The impedance of an electric circuit is the measure of the opposition presented by a circuit when the current and voltage is applied.
What is the definition of impedance in physics and how does it relate to the flow of current in an electrical circuit?
Impedance in physics refers to the measure of opposition to the flow of alternating current in an electrical circuit. It includes both resistance and reactance. In simple terms, impedance determines how much a circuit resists the flow of current, affecting the overall behavior of the circuit.
What is the term for opposition to current flow within a circuit?
The term Impedance (Z) is used to quantify the opposition to current flow in a circuit.
What is an opposition to current flow called that occurs in an alternating current circuit?
The resistance is called impedance, and is equal to the measured voltage divided by the measured current, through Ohm's Law (V = ZI, Z = V/I).
An opposition to current flow that occurs in alternating current circuits is called?
Capacitive reactance.
What is it mean to say that an alternating current leads or lags an alternating emf?
It is another way of saying that the circuit is capacitive reactive circuit. Look up the mnemonic ELI the ICE man. ELI, voltage leads the current in an inductive circuit. ICE, current leads the voltage in a capacitive circuit.
What is the opposition to flow of current in a circuit called?
The opposition to the flow of current in a circuit is called resistance. Resistance is measured in ohms and is represented by the symbol Ω.
What is the significance of impedance in electrical circuits and how does it affect the flow of current?
Impedance in electrical circuits is important because it measures the opposition to the flow of alternating current. It consists of resistance and reactance, which affect how current flows through a circuit. A higher impedance means there is more resistance to the current flow, which can limit the amount of current that can pass through the circuit. This can impact the efficiency and performance of the circuit.
When current in a circuit reverses its direction in a regular pattern it is called?
An "Alternating Current" (AC).
Which is a circuit used to change alternating current to direct current?
Insufficient information given.
