OHM'S LAW
Definitions In mathematical problems, emf (voltage) is expressed in volts, and the symbol used is E. R is the symbol for resistance which is measured in ohms. The symbol for current is I, which is measured in amps. The letter symbols E, R, and I have an exact relationship in electricity given by Ohm's law. This law may be stated as follows: The current in an electric circuit is directly proportional to the emf (voltage) and inversely proportional to the resistance. Ohm's law is further expressed by the statement:
