I’ve been working with dc power supplies and batteries for over 30 years now and every day I employ Ohm’s Law, V = I*R, to solve some problem or make some calculation related to dc power. If current is flowing, then there’s a voltage drop in the wires, in the connectors, in the relays, in the resistors, or in other circuit components. The more current, the bigger the voltage drop. The more resistance, the longer the wires, the thinner the wires, the more in-line connection
