Explanation:

1. Alessandro Volta invented the first electric battery in 1800, and the unit "volt" is named after him.
2. Georg Ohm defined the relationship between power, voltage, current, and resistance in 1826 (Ohm's Law).
3. Joseph Henry invented the electrical relay in 1835.
4. Charles Brush invented the open - coil dynamo in 1876.
5. Thomas Edison opened the Pearl Street Station in 1882, which used direct current.
6. Nikola Tesla invented the electric alternator to produce alternating current in 1884.
