Question

UI
Calculate electric potential at a distance 'r' from a point
charge 'q'.
(C) Calculate Capacitance of a isolated conductor of
radius 'R', Capacitance of a capacitor is 2 uF, when a
dielectric slab of thickness 34 d is inserted between the
plates, then its capacitance becomes 4uF , find K.​

Answer 1

Answer:

The stored electric charge in a capacitor, Q (in coulombs, abbreviated C) is equal to the product of the capacitance C (in Farads, abbreviated F) of the capacitor, and the voltage V (in volts, abbreviated V) across its terminals. That is, Q = C٠V. For example, if C = 33uF and V = 20V, then Q = (33٠10^-6)٠(20) = 660uC.
