    Doubt Inductor
Click For Summary
In an AC circuit with a pure inductor, the instantaneous EMF generated by the changing magnetic field equals the back EMF, which can lead to confusion about current flow. The relationship between current and voltage in an inductor is described by the equation V = L (di/dt), where V is the voltage across the inductor, L is the inductance, and di/dt is the rate of change of current. While the back EMF opposes the applied voltage, it does not mean that the net potential difference is zero; rather, the current can still flow due to the continuous change in current over time. The key point is that the back EMF is a result of the inductor's response to changes in current, allowing for current flow despite the opposing EMF. Understanding this dynamic is crucial for analyzing AC circuits with inductors.

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?
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
