Question 6

Derive the expression for the capacitance of a configuration where two plates are kept distance d apart when a material of thickness t with dielectric constant K is inserted in-between.

Question 7

Derive the magnetic field B of a Toroid by using Ampere’s circuital law.

Question 8

State the Ampere circuital law and define magnetic flux. State the right hand thumb rule for magnetic field created by electric current. From the Lorentz Force expression derive the force acting on a current element of length l by a magnetic field B. More…
