When electricity was first introduced to towns,?
When electricity was introduced to towns and city's back in the good old days, what wattage and voltage did they have? Could you plug today's lamp into the socket and have it work, or was it different current?
Answer:
most places instituted DC current. Things were wired in series circuits.
Voltage varied from place to place, but was close to either 12 or 24 volts.
It was only for lighting purposes.
There was no outlet to plug into.
Knob and Tube was the term for the wiring method.
It was all exposed in the plaster walls.
Im an electrician and I run into it from time to time in really old homes.
Baltimore city used DC at 12 volts in the mid 1800's
I think it was the same, but I'm not 100% positive. However, the way buildings were wired was different. They had one circuit and everything was on just the one path so when one light bulb would blow out, you had to go through all of the items attached into the circuit to see which one needed replacing. Just like a string of Christmas lights. Then they figured out how to put in parallel circuits and it improved things.

History
Centralized power generation became possible when it was recognized that alternating current electric power lines can transport electricity at low costs across great distances by taking advantage of the ability to transform the voltage using power transformers.
Electricity has been generated for the purpose of powering human technologies for at least 120 years from various sources of energy. The first power plants were run on wood[citation needed], while today we rely mainly on coal, nuclear, natural gas, hydroelectric, and petroleum power and a small amount from solar energy, tidal harnesses, wind generators, and geothermal sources.
