Afghan Farmers: Opium Is The Only Way To Make A Living. Afghan Farmers: Opium Is The Only Way To Make A Living. An Afghan farmer collects raw opium as he works in a poppy field in Nangarhar province on April 29. Poppy cultivation reached a record high this year despite Western efforts to reduce it.

Best Answer: 1. voltage on a cap, charging v = vâ[1âe^(ât/Ï)] vâ is the final voltage 2. voltage on a cap, discharging v = vâe^(ât/Ï) vâ is the initial voltage on the cap R is resistance in ohms, C is capacitance in farads t is time in seconds RC = Ï = time constant v = vâe^(ât/Ï) v/vâ = e^(âÏ/Ï) = 1/e = 0.368.
1) C- capacitors in series have opposite sign charges on each adjacent plate but the same magnitude of charge on each plate. 2) B- C = Q/delta V Q/C = delta V Since they all have the same charge on them, the voltage drop across each capacitor is proportional to 1/C. Since you have C on the first one, then having 2C and 3C on the other two means your voltage will be 1/2 and 1/3 of the voltage of the first one.
