Ohms law: Learn the basics of Ohms '

Learn the basics of Ohms ' law , the fundamental law of electrical circuits that relates voltage, current and resistance. Find out how to use the formula, the theory and the examples to calculate and understand the circuit behavior. Theory Ohm's Law The law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Such a conductor is characterized by its ‘Resistance’ – R measured in Ohms . V=I×R V is the Voltage in Volts across the conductor. I is the current in Amperes through the conductor. Voltage (V) is directly proportional to current i.e V=I×R. Resistance (R) in inversely proportional to current (I) i.e I = V R A SIMPLE explanation of Ohm's Law . Learn what Ohms Law is, how it works, the formula and triangle for Ohm's Law , and practice problems. We also discuss how in physics ... Ohm’s Law is a fundamental principle in physics and electrical engineering. It describes the relationship between electrical voltage, current, and resistance in an electrical circuit.
