ETFL 60 = Elevated Temperature Flame Limit @ 60 Â°C. HOC = Heat Of Combustion. Compounds used as refrigerants may be described using either the appropriate prefix above or with the prefixes R- or Refrigerant.. Thus, CFC-12 may also be written as R-12 or Refrigerant 12.An alkene, olefin, or olefine is an unsaturated chemical compound containing at least one carbon-to-carbon double bond.hemical refrigerants are assigned an R number which is determined systematically according to molecular structure.
Energy stored in a capacitor. The energy stored in a capacitor is the same as the work needed to build up the charge on the plates. As the charge increases, the harder it is to add more. Potential energy is the charge multiplied by the potential, and as the charge builds up the potential does too.
e. What are the charge and current as functions of time? f. How much energy is stored in the capacitor when it is fully charged? a. The energy stored in this system is given fromU = 1 2 CâV 2 so that the potential difference is âV = 2U C = 23()00 J 30 Ã10â6 CV = 4.47 Ã103 V b. The time constant is given asÏ=RC =47Ã103Î©Ã32Ã10â6 F =1.5s. c. The maximum charge on the capacitor is the product of the capacitance and the
