Batteries, current, and Ohm''s law
A copper wire has a length of 160 m and a diameter of 1.00 mm. If the wire is connected to a 1.5-volt battery, how much current flows through the wire? The current can be found from Ohm''s Law, V = IR. The V is the battery voltage, so if R can be determined then the current can be calculated.
