  1. Define Capacitance and the Farad

  2. G482 Module 2 - Capacitors

  3. Module 2: Capacitors Create an analogy to describe the movement of charge within a capacitor Select(and use) an appropriate equation for calculating the charge stored on a capacitor Definecapacitance and the farad E/D B/A A

  4. Capacitance and the Farad The charge stored per unit potential difference, as given by C = Q/V. Unit of capacitance (F). 1 F is 1 C of charge stored per volt.

  5. Potential difference against charge graph W V Q

  6. Module 2: e-capacitors Analyse the discharge of a capacitor after a time, t. Usethe RC circuit time constant, τ, where appropriate. Describean exponential decay E/D B/A A

  7. * *If you’re under 18 beer is horrible, if you’re over 18 beer is awesome

  8. h0 h = h0 e-λt h t0 t

  9. X0 X = X0 e-t/CR I = I0 e-t/CR Q = Q0 e-t/CR V = V0 e-t/CR For radioactive decay A = A0 e-λt X t0 t

  10. Module 2: e-capacitors Analyse the discharge of a capacitor after a time, t. Usethe RC circuit time constant, τ, where appropriate. Describean exponential decay E/D B/A A
