As in other autoimmune diseases such as lupus and rheumatoid arthritis, the bodyâs natural ability to attack invading viruses and bacteria goes haywire and mistakenly sees healthy body proteins as enemies. Redness, pain, heat and swelling signal that the immune system is on the warpath.
Formal Charge = [# valence electrons on neutral atom] â [(# lone electron pairs) + (Â½ # bonding electrons)] 1  Valence electrons = corresponds to the group number of the periodic table (for representative elements).  Lone Pairs = lone electrons sitting on the atom. Each electron counts as one and so a pair counts as two.
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
