Inductor Doubt: Instantaneous EMF=Back EMF?

In summary, an inductor is an electronic component that stores energy in the form of a magnetic field and is used to control the flow of current in circuits. An instantaneous EMF is the voltage generated in an inductor at a specific moment in time, caused by a change in current. Back EMF is the voltage induced in an inductor when the current flow is interrupted or changed, in the opposite direction of instantaneous EMF. These two values are equal in magnitude but have opposite directions. Understanding this relationship is crucial in designing and analyzing electronic circuits, ensuring proper functioning of devices and systems.

Doubt on Inductor!pleasez help

Imagine an AC source and a pure inductor...if the Instantaneous EMF=Back EMF due to changing Magnetic field in Inductor then how does the current flow?

What is the equation for the relationship between current and voltage for an inductor?

I meant that if the back emf = applied voltage always then the net PD=0..so how can the current flow?
 

FAQ: Inductor Doubt: Instantaneous EMF=Back EMF?

What is an inductor?

An inductor is an electronic component that stores energy in the form of a magnetic field. It is made up of a wire wound into a coil and is typically used in circuits to control the flow of current.

What is an instantaneous EMF?

An instantaneous EMF (electromotive force) is the voltage that is generated in an inductor at a specific moment in time. It is caused by a change in the current flowing through the inductor.

What is back EMF?

Back EMF, also known as counter EMF, is the voltage that is induced in an inductor when the current flow through it is interrupted or changed. It is in the opposite direction of the instantaneous EMF.

How is back EMF related to instantaneous EMF?

In an inductor, the instantaneous EMF is equal to the back EMF at any given moment. This means that the two values are equal in magnitude but have opposite directions.

Why is understanding inductor doubt and instantaneous EMF important?

Understanding inductor doubt, specifically the relationship between instantaneous EMF and back EMF, is crucial in designing and analyzing electronic circuits. It helps engineers predict and control the behavior of inductors in circuits, ensuring the proper functioning of devices and systems.
