Ohm’s Law and Definitions of Voltage, Current and Resistance in a Circuit

Ohm's Law

Georg Simon Ohm, a famous German physicist and mathematician, gave  an important concept about electrical circuits, known as  Ohm’s Law.  According to this law, the current in a circuit is directly proportional to the voltage applied to the circuit and it is  inversely to the resistance. Relationship between Voltage and Current: According …
