In the equation, the constant of proportionality, R, is called Resistance and has units of ohms, with the symbol Ω. The same formula can be rewritten in order to calculate the current and resistance respectively as follows: Ohm’s law only holds true if the provided temperature and the oth...
The conductive path provides a resistance (R). In the diagram, this is aresistorsymbol but could be any passive or active load. An ammeter (A) measures the resulting current through the circuit in amperes. By adjusting the voltage source and measuring current, the resistance R can be empiric...
current. Ohm's name has been incorporated in the terminology of electrical science in Ohm's Law (which he first published inDie galvanische Kette mathematisch bearbeitet), the proportionality of current and voltage in a resistor, and adopted as the SI unit of resistance, the ohm (symbol Ω)....
A note for readers who are not familiar with angle notation used in American textbooks on electronics and electrical engineering. A special notation called phasor or angle notation is used with the angle symbol (∠). It is used to describe phasors. A phasor is a complex numberUused to repres...
Commonly referred to by the symbol P, power is a crucial measurement in electrical engineering that affects how components are designed, how they operate, and how long they last. The relationship between power (P), voltage (E), and current (I) is fundamental to understanding how electrical ...

In schematic diagrams, resistor symbols are sometimes used to illustrate any general type of device in a circuit doing something useful with electrical energy. Any non-specific electrical device is generally called a load, so if you see a schematic diagram showing a resistor symbol labeled “load...
