But how can we assume electric field to be constant when the charge is changing? The electric field in a capacitor is σ/ε. σ arial charge density. If we use that, then:
Φ = A.E
= Q/ε
Now differentiating,
(dΦ/dt) = (DQ/dt)/ε
So ε(dΦ/dt) = (DQ/dt)
Hence Idisplacement is dq/dt following which I...
I'm a student from India and I'm studying to clear the IIT-JEE. I study physics, chemistry, maths, and computer science. I enjoy physics and computer science and I want to work in either of these fields. I also enjoy mathematics but my aptitude is not in it. Inorganic chemistry is not my area of...
