For my senior year, the school sprang for a FORTRAN compiler to run on the business office NCR computer. My job was to run the students punch-card decks through the computer during the business office lunch hour. Spent an interim month learning to use FORTRAN as a language usage analysis tool, under tutelage of a Classic Languages professor.
electric forces can be attractive or repulsive, whereas gravitational forces are only attractive.
The voltage between two points is equal to the electrical potential difference between those points. It is actually the electromotive force (emf), responsible for the movement of electrons (electric current) through a circuit.n other words, current is the rate of flow of electric charge. Voltage, also called electromotive force, is the potential difference in charge between two points in an electrical field.
