Batteries, current, and Ohm''s law
Ohm''s law is one of the basic principles of electricity. It relates the basic parameters of electricity, Current and voltage, to each other and with resistance. Georg Ohm, after whom the law was named, conduct a few experiments on circuits containing different lengths of wires and found that the voltage applied and current are directly proportional.
