According to ohms law Proportional. Ohms law: V = I*R
and voltage drop, the More current makes more voltage drop. This is a
relationship between reason why we need a larger wire with more current,
voltage drop and current so the wire resistance is less with a larger wire and
is there will be less voltage drop.
