Ohms law is one of the most important concepts in electronics. Ohms law gives relationship between current, voltage, and resistance.
|"The amount of current flowing in a circuit is directly proportional to the electromotive forces impressed on the circuit and inversely proportional to the total resistance of the circuit."|
According to the Ohms law, voltage equals current times resistance which is expressed in the following equation:
where E = voltage, I = current, and R = resistance
