Topics covered in Electrostatic Potential and Capacitance for KEAM Physics.
Topics in Electrostatic Potential and Capacitance
Electrostatic Potential and Potential Difference
- Electric potential at a point is the work done per unit charge in bringing a positive test charge from infinity to that point
- Potential difference between two points is the work done per unit charge in moving a charge from one point to another
- Electric potential is a scalar quantity with SI unit volt (V) where 1V = 1J/C
Potential due to Different Charge Configurations
- Potential due to point charge: V = kQ/r
- Potential due to system of charges: algebraic sum of individual potentials
- Potential due to electric dipole varies with position and angle
Potential Energy and Work in Electric Fields
- Potential energy of two-charge system: U = kq₁q₂/r
- Work done by electric field is negative of change in potential energy
- Potential energy of dipole in external field: U = -p⃗·E⃗ = -pE cosθ
Capacitance and Capacitors
- Capacitance C = Q/V is the ability to store charge per unit potential
- Capacitance depends on geometry and dielectric material, not on charge or voltage
- Parallel plate capacitor: C = ε₀A/d
