CAPACITORS AND DIELECTRICS
CAPACITANCE
the ratio of the number of charges on each conductor to the potential difference between them
Q = CV
1 Farad = 1 Coulomb per volt
CAPACITORS WITH DIELECTRICS
the function of dielectric in a capacitor
prevents breakdown of capacitors
allows bearing positive and negative charges to be placed at a close distance without touching
increase the capacitance of a capacitor by a factor of k, the dielectric constant
the electric field in parallel plate capacitor due to the presence of dielectric
the capacitance of a parallel plate capacitor with dielectric
PARALLEL PLATE CAPACITORS
capacitance of parallel plate capacitors
C = Q/V = e0A/d
capacitance of concentric sphere
ENERGY STORED IN A CHARGED CAPACITORS
energy storage
electric field energy or energy density
CHARGING AND DISCHARGING OF CAPACITORS
charging of capacitors
the time dependant factor for charging of capacitors
discharging capacitors
energy consideration for charging and discharging of capacitors
CAPACITORS IN SERIES AND PARALLEL CIRCUITS
capacitors in series
Veq = V1 + V2 + V3 + ...
1/Ceq = 1/C1 + 1/C2 + 1/C3 + ...
Q = Q
capacitor in parallel
V = V
Ceq = C1 + C2 = C3 + ...
Qeq = Q1 + Q2 + Q3 + ...
