- 1Shape of a Q-t graph charging and discharging (capacitors) + equations{to be inserted}
- 2Shape of a I-t graph charging and discharging (capacitors) + equations{to be inserted}
- 3Shape of a V-t graph charging and discharging (capacitors) + equations{to be inserted}
- 4Definition of capacitanceThe charge stored per unit potential difference across a capacitor
- 5What happens to half of capacitor energy during charging?1/2 energy is always 'lost' due to heat in wires and/or resistor:
E=1/2QV or E=1/2 CV^2 or E=1/2Q^2/C - 6Which capacitance equation is for series and parallel?C1+C2+C3=Ct -->in parallel
(1/C1)+(1/C2)+(1/C3)=1/Ct -->in series - 7What is relative permittivity?
- 8Definition of electric field strengthThe force experienced per unit positive charge at that point
- 9What equation for energy involves charge?E=QV
(energy = charge x p.d) - 10—
