torc on which​

Answer 1

Answer:

In particular it includes the resistivity of copper, the resistivity of aluminium, gold and silver. ... In order to compare the capability of different materials to carry electrical current, figures for the resistivity are used. ... The definition of resistivity states that the resistivity of a substance is the resistance of a ... Nichrome, 1.1 x 10-6.

The coulomb, also written as its abbreviation 'C', is the SI unit for electric charge. 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.
