WebAug 6, 2024 · Ohm’s Law Ohm’s law states that current in a resistive circuit is directly proportional to the applied voltage and inversely proportional to resistance. Ohm’s law is also expressed in the following forms: Two different symbols are commonly used to represent voltage: • E for sources • V for loads (e.g., the voltage drop across a resistor) WebOhm expressed his discovery in the form of a simple equation, describing how voltage, current, and resistance interrelate: In this algebraic expression, voltage (E) is equal to current (I) multiplied by resistance (R). Using algebra techniques, we can manipulate this equation into two variations, solving for I and R, respectively:

WebMar 11, 2024 · The three main quantities are voltage, current and resistance. Ohms’s law uses a simple triangle to make it extremely easy to use the equation. The formulas for Ohms law look like this: I = V/R or V = IR or R = V/I. I = Current. V = Voltage. R = Resistance. Ohm’s law triangle. WebGeorg Simon Ohm was a German physicist, best known for his "Ohm's Law", which states that the current flow through a conductor is directly proportional to the potential difference (voltage) and inversely proportional to the resistance. The physical unit of electrical resistance, the Ohm (symbol: Ω), was named after him.
