What device measures electric current? ammeter, instrument for measuring either direct or alternating electric current, in amperes. An ammeter can measure a wide range of current values because at high values only a small portion of the current is directed through the meter mechanism; a shunt in parallel with the meter carries the major portion.
Why was the Telegraph important to the industrial revolution? The ability to communicate across long distances improved dramatically during the Industrial Revolution. It began with the invention of the electrical telegraph by Samuel Morse in 1844. This system allowed for messages to be transmitted much quicker and cheaper than old methods.
How did Telegraph impact society? As the first means of long-distance communication, the telegraph changed the shape of American society. The telegraph expanded the business possibilities and expedited the work of a variety of professions, including bankers, brokers, lawyers, and hotel proprietors.
