electrostatic potential and capacitance

Slide 1

• electric forces are conservative in nature.
• work done against the force is stored in the form of potential energy.
• electric potential energy and electric potential are both relative values and not absolute.
• at infinity potential, energy or potential is zero
• units of potential is- joule per coulomb or volt
• dimension is ML^2 T^-3 A^-1
• 
• Legenda: potential formula
