2020-4-18The electrical resistance of an electrical conductor is a measure of the difficulty of passing an electric current through that conductor. It explains the relationship between voltage amount of electrical pressure and the current flow of electricity. With more resistance in a circuit less electricity will flow through the circuit. Resistance discovered by Georg Simon Ohm in 1827 is the
