By indirect solution i meant,
V= E*d
Where E is the electric field between the two plates.
And d is the distance of separation of plates.
And by a direct solution I meant finding the potential difference just by using the variables, charge Q on the plate, the distance of separation d between...
How do we find out the potential difference between two equal and opposite charged (conducting) parallel plates mathematically? Let the charge on a plate be 'Q', Total area of a plate be 'A', the distance between the plates be 'd'.
I need a direct mathematical solution please, I've come across...
