One coulomb is equal to the amount of charge from a current of one ampere flowing for one second. One coulomb is equal to the charge on 6.241 x 1018 protons. The charge on 1 proton is 1.6 x 10-19 C. Conversely, the charge of an electron is -1.6 x 10-19 C.
Is split system heating expensive to run?
If you are wanting to cooling or heat up a fairly large area of space, you should get a bigger system as splits comes in small. The fact that split systems uses reverse cycle as explained above, it means that they are not the cheapest option to run even though they are cheap to purchase.

How do I know if my heater is leaking carbon monoxide?
Other possible signs of carbon monoxide are: Streaks of soot around furnace; Absence of an upward draft in your chimney; Excess moisture found on windows, walls, or other cold surfaces; Excessive rusting on flue pipes, other pipe connections, or appliance jacks; Small amount of water leaking from the base of the …
What is the safest heating system?
#1: Electric Heat Electric furnaces, baseboard heaters, and other heating methods that use electricity are among the most efficient and safe heating methods. As most are controlled by thermostats located in each room, electric heating systems are precise, working only when needed.
