what are variable charged ions?

Answer 1

Elements which have more than one common oxidation state. For example, iron exists as both the iron (II) or ferrous ion, Fe2+, as well as the iron (III) or ferric ion, Fe3+. Many other transition elements have more than one oxidation state (e.g. Co, Mn) as well as main group elements like lead (Pb2+ and Pb4+) and tin (Sn2+ and Sn4+).

Answer 2

You omit the element. excessive voltage is used, in lots of situations, to minimize the present requirement for ability transmission. you like a definite volume of ability. that particular same ability could be delivered utilising low voltage and excessive cutting-edge, or excessive voltage and espresso cutting-edge. you like the low cutting-edge option each and every time achievable, because of the fact cutting-edge produces IR losses. Do the mathematics. in case you have a similar volume of resistance (R), do you lose extra ability with an superior or decrease cutting-edge? i.e., for a 1000W requirement (or load), you may have: 100v x 10A = 1000W or 1000V x 1A = 1000W. yet what have you ever gained? anticipate the transmission line has a resistance of .one million ohm. 10A x 10A x .one million ohm = 10W loss (I^2 x R = W) or 1A x 1A x .one million ohm = .1W loss. the terrific wager is the better voltage for a extra effective pass of ability to the burden. The call for from the flexibility supply is set via the burden standards. you won't be able to plug a 110v device right into a 1000v outlet. i'm no longer asserting that. we are speaking approximately shifting ability from the flexibility station to the top consumer. There are different issues, which comprise safety, yet it is the fee you pay to pass the flexibility. You adjust for that. i'm hoping this helps.
