What are the cause of induced emf?
A change in current causes a voltage to be induced into an inductive circuit, which opposes that change of current. This is because the change in current is accompanied by a change in magnetic flux which 'cuts' the conductors and induces a voltage into them.
What is the difference between an inductor and a capacitor?
Firstly the suffix '-ance' in each of those three words indicate the properties the material exhibits. Therefore resistance is the property by which any material tends to oppose the flow of current through it. Inductance is the property by which a material opposes the change in current, or opposes an alternating current. An inductor can be appreciated simply using a coil of insulated wire, or a solenoid. Capacitance is the property by which a material opposes the change in voltage across its ends, ie how it opposes alternating voltage. A capacitor comprises of, essentially, two metallic plates separated by a dielectric (a medium which may/may not be non-conducting, but is capable to contain charge). cheers!!
What is a series reactor?
series reactor is used to limit the fault current. b'cos reactor contains inductance and it opposes the rate of change of current
An inductor is a device that opposes the?
An inductor is a passive electronic component that opposes changes in current flow through it. It accomplishes this by inducing a voltage that is proportional to the rate of change of current passing through it. The main property of an inductor is its inductance, which is a measure of its ability to store energy in a magnetic field. As a result, an inductor opposes changes in current by generating a back electromotive force (EMF) in the opposite direction of the applied voltage. This opposition to changes in current is often referred to as inductive reactance. Specifically, an inductor opposes: Changes in Current: When an electric current through an inductor increases, the inductor creates a magnetic field that stores energy. This energy is released when the current decreases, which opposes the decrease in current. Similarly, when the current decreases, the inductor generates a voltage to maintain the current flow, opposing the change. Alternating Current (AC): In an AC circuit, the current periodically changes direction. An inductor resists these changes and limits the rate at which the current can change. It effectively smoothens out variations in the current and behaves as a low-pass filter, allowing lower frequency components to pass while attenuating higher frequency components. Voltage Transients: Inductors also oppose sudden changes in voltage, commonly known as voltage transients or spikes. When a sudden voltage change occurs, the inductor generates an opposing voltage to mitigate the effect of the transient and limit the rate of change of the current. In practical applications, inductors are used in various electronic systems and devices. They are employed in power supplies, signal filtering circuits, motor control circuits, transformers, and many other applications where controlling current, energy storage, and voltage regulation are important.

What is the maximum inductor voltage when the inductor current is decreasing?
depending on the stray capacitance it can be from a few ten volts to a few kilo volts.
Is electrical conductivity a chemical change?
No, electrical conductivity is a physical property that depends on the ability of a material to carry an electric current. It is not a chemical change because the chemical composition of the substance remains the same.
An inductor opposes a change in?
current flowing through it by inducing a voltage that creates a magnetic field, which stores energy. This property of inductors results in opposition to changes in current, which is described by Faraday's law of electromagnetic induction.
What is the concept of self-inductance of a wire and how does it affect the behavior of the wire in an electrical circuit?
Self-inductance is the property of a wire to generate a magnetic field when current flows through it. This magnetic field induces a voltage in the wire itself, which opposes the change in current. This can cause delays in the flow of current and affect the behavior of the wire in an electrical circuit, leading to phenomena like inductive reactance and energy storage in the magnetic field.
What is magnetoresistence?
The change in electrical resistance produced in a current carrying conductor or semiconductor on application of magnetic field H.
What is the unit to measure the opposition to the flow of electrical current called?
Answer: Inductive reactance is the opposition to the change in current in an electrical circuit and is abbreviated Xl. Answer: The opposition to current flow is called resistance (for DC), or impedance (for AC; often just called resistance); the unit for both is the ohm.
What are the cause of induced emf?
A change in current causes a voltage to be induced into an inductive circuit, which opposes that change of current. This is because the change in current is accompanied by a change in magnetic flux which 'cuts' the conductors and induces a voltage into them.
How can one determine the direction of induced current in a circuit?
The direction of induced current in a circuit can be determined using Lenz's Law, which states that the induced current will flow in a direction that opposes the change in magnetic field that caused it. This means that the direction of the induced current will be such that it creates a magnetic field that opposes the original change in magnetic field.
How does a resistor slow down the flow of change in a circuit?
A resistor slows down the flow of current in a circuit by converting electrical energy into heat. This conversion of energy leads to a loss in voltage, limiting the speed at which the current can flow through the circuit. The resistance in the resistor opposes the flow of current, reducing its rate of change.
What does the lenz law state?
The direction of an induced emf or current is such that the magnetic field created by the induced current opposes the change in magnetic flux that created the current.
What is the statment of lenz law?
The direction of an induced emf or current is such that the magnetic field created by the induced current opposes the change in magnetic flux that created the current.
What is the direction of the induced current in a loop when there is a change in magnetic field direction?
When there is a change in the direction of the magnetic field in a loop, an induced current is generated in the loop in a direction that opposes the change in the magnetic field.
