q=me
F=kq1q2÷r^2
Fvac=ErFmed Er is relative permitivity
F=qoE
E=kq÷r^2
phi=E.A cos theta
phi=q÷Eo
E=sigma÷2epislon knot(electric field intensity due to infinite sheet of charge)
E=sigma÷epsilon knot(electric field intensity between two oppositely charged parallel plates)
V=kq÷r
E=_V÷r
C=Q÷V
C=Q÷V=EoA÷d
Cmed=EoEr÷d
1÷Ce=1÷C+1÷C2.......(capacitance of a series combination)
Ce=C1+C2........ (capacitance in parallel combination)
U=CV^2÷2
