# Ohm meaning

**Ohm's Law**The equation "R=V/I" is the more streamlined version of the one developed by German physicist Georg Simon Ohm in 1827. Ohm's law is used to calculate the resistance in materials such as metal, which maintain a linear relationship between voltage and current. In addition, Ohm's formulas, which are derived from Ohm's Law, are used to calculate voltage and current if the other two measurements are known.

**OHM'S LAWw**

**Resistance = voltage divided by current**R = V / I or R = E / I

**OHM'S FORMULAS**

**Voltage = current times resistance**V = I * R or E = I * R

**Current = voltage divided by resistance**I = V / R or I = E / R V or E = voltage (E=energy) I = current in amps (I=intensity) R = resistance in ohms

**Electric Power**

**Power in watts = voltage times current**P = V * I.

**)**The unit of both resistance (R) and impedance (Z). In the International System of Units (SI), one (1) ohm is the resistance such that a difference in potential of one (1) volt (V) between the positive (+) end and the negative (
