WebThe inventor Otis Frank Boykin, known for inventing the wire precision resistor, was born on August 29, 1920 in Dallas, Texas. Boykin’s mother, Sarah Boykin, worked as a maid before dying in 1921 before Boykin’s first birthday. Boykin’s father, Walter Boykin, worked as a carpenter and later became a minister. Georg Simon Ohm was a German physicist and mathematician. As a school teacher, Ohm began his research with the new electrochemical cell, invented by Italian scientist Alessandro Volta. Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This rela…
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
