What is opposition to an alternating current due to inductance or capacitance called?
In electric and electronic systems, reactance is the opposition of a circuit element to the flow of current due to that element’s inductance or capacitance. Greater reactance leads to smaller currents for the same voltage applied.
What is the opposition offered by an inductance to the flow of alternating current through it?
This opposition is called inductive reactance, symbolized by XL, and is measured in ohms. This characteristic of the inductor may also create a phase shift between voltage and current of the circuit.
What is the opposition to current flow in an AC circuit?
The total opposition to current flow in an AC circuit is known as impedance and is represented by the letter Z. The combined effects of resistance, inductive reactance, and capacitive reactance make up impedance (the total opposition to current flow in an AC circuit).
What is the opposition to the AC by inductor called?
The opposition to current flow through an AC Inductor is called Inductive Reactance and which depends lineally on the supply frequency.
Is the opposition of current flow?
A resistive circuit opposes current directly. A reactive circuit transforms current and creates opposition to current flow in the process. The resultant opposition to current flow is called “capacitive reactance.”
What is total effective opposition to alternating current?
The total effective opposition offered by LCR circuit to alternating current is known as impedance. This note provides us an information on A.C. through an inductance, capacitance and resistance.
When to use reactance and resistance in a circuit?
When dealing with frequencies greater than zero (alternating current or AC), we find that resistance alone is insufficient to properly quantify the total opposition to current flow in a circuit. This leads us to reactance.
What is the opposition to current flow in an AC inductor?
The opposition to current flow through an AC Inductor is called Inductive Reactance and which depends lineally on the supply frequency
What is the ratio of inductance, capacitance and resistance?
Inductance, capacitance and resistance • Power factor is 100% in DC circuits. • It is the ratio of apparent power to true power. Inductance, capacitance and resistance • Apparent Power is that derived from measuring voltage and current in an AC circuit and multiplying them.
