Explanation of flow of current through capacitor
expressionfor displacement current.
During charging, electric flux between the plates of capacitor keeps onchanging this results in the production of a displacement current between the plates.
`I_(d)=epsilon(d varphi_(E))/(dt)(I_(d)=epsilon_(0)A (dE)/(dt))`
