I assume you are asking about inductors... The inductor has a winding, sometimes around a ferrous core. Current flow creates a magnetic field. When you try to change the current, the magnetic field changes, but that magnetic changing resists the change in current. Mathematically, this is expressed as di/dt = v*L, or Rate of change of Current is equal to Voltage * Inductance. So, the larger the Inductance, the harder it is (requiring larger Voltage) to change Current.

What is spike current?
A spike is a sudden rise in current that then goes back to normal. Usually caused by a sudden increase in voltage that could be caused by a lightening strike, for example.
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.

The ability of conductor to induce voltage in itself when the current changes?
The ability of conductor to induce voltage in itself when the current changes is called inductive reactance.
What are the two kinds electricity?
Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction. In AC (alternating current), the current regularly changes its direction.Perhaps you are referring to DC and AC? DC is direct current - current flows in a single direction.

Electric current changes direction repeatedly is called?
AC current (alternating current) like in a wall outlet
What is a sign that a person may need help for a mental disorder?
Experiencing sudden changes in interests or hobbies (APEX)
What is the manager role in sudden changes?
The role of a manager in sudden changes is to ensure that there is a smooth transition. The manager has the duty to ensure that all departments adapt to the changes swiftly.

What are all signs of indicating sudden emotions?
Signs of indicating sudden emotions include changes in facial expression (such as wide eyes or a furrowed brow), changes in voice tone or volume (like raised pitch or yelling), increased heart rate and breathing, and physical movements (like pacing or fidgeting). Other signs may include sweating, blushing, or sudden changes in behavior.
What is the effect if there is a sudden flow of electric current?
electric shock
What are the signs of approaching wheather?
changes in windspeed or direction, sudden changes in air pressure or temperature. Or humidity.
When electric current changes direction is called?
When electric current changes direction, it is called alternating current (AC).
What affects the slow Chang of evolution?
sudden changes in the enviornment........???i think???:)
What r the uses of tangent galvanometer?
to detect the sudden change in current.
How do detect a microburst?
Microbursts can be detected using weather radar. A sudden and intense downward air current can cause a radar signature called a radar wind shear pattern. Pilots may also detect a microburst while in flight due to sudden changes in airspeed, altitude, and wind direction.
Why are dramatic sudden changes in personality difficult to believe?
Dramatic sudden changes in personality are difficult to believe because they typically go against the idea that personality is stable and consistent over time. People tend to view personality as relatively fixed, developed over a long period, so abrupt changes can be seen as out of character. Additionally, sudden changes may raise questions about authenticity and trustworthiness, leading to skepticism.
