Aparallel-plate capacitor with circular plates of radius 0.19 m is being discharged. a circular loop of radius 0.28 m is concentric with the capacitor and halfway between the plates. the displacement current through the loop is 2.6 a. at what rate is the electric field between the plates changing?

Explanation:

Given that

R= 0.19 m

r= 0.28 m

I= 2.6 A

We know that

A= Area of loop

dE/dt= rate of change of electric filed

I=Displacement current

Here r>R

So A=π R²

Now by putting the values

what type of charge does it have? negative

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
