Hernando builds a simple DC series circuit with a standard D-cell battery and uses an ammeter to determine that the total current in the system is 3.0 A. In an attempt to increase the brightness of the bulbs in the circuit, he tries to increase the voltage by adding two more batteries (in series with the first). Calculate the new current when driven by three batteries.
