One wire in a circuit is replaced by a wire that conducts less electricity. which unit describes the difference in conduction between the wires ? plato answer is c. ohms

Conductivity of two wires is compared by the resistance of wires

Resistance is measured in unit "ohm".

If resistance of a wire will be more then it will conduct less electricity.

So if a wire in the circuit is replaced by another wire then current will be less if more resistance of wire will be there.

So wire conducts less electricity then its resistance will be more

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
