Is Resistance Dependent On Length?

by

Is Resistance Dependent On Length? The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor. Does length increase resistance? First, the total length of the wires will affect the amount of resistance. The longer the wire, the more

What Charges Are Free To Move In A Metal?

What Charges Are Free To Move In A Metal? Metals atoms have loose electrons in the outer shells, which form a ‘sea’ of delocalised or free negative charge around the close-packed positive ions. These loose electrons are called free electrons. They can move freely throughout the metallic structure. Do metals have free moving ions? Although
