Capacitance

What is capacitance

• coulomb on plate holding until full then pissing onto other plate

Parallel plate capacitor

• How can we find the electric field

  • $C=\frac{{ϵ}_{0}A}{d}$
    • where A is area and d is distance between the two plates
  • $E=\frac{\sigma }{{ϵ}_0}=\frac{Q}{{ϵ}_{0}A}$
  • $V=Ed$
