The power dissipated by a resistor may be calculated from its resistance, and the voltage or current involved. The formula is a combination of Ohm's law and Joule's law: where P is the power, R is the resistance, V is the voltage across the resistor, and I is the current through the resistor. A linear resistor has a constant resistance value over all applied voltages or currents; many pract… WebElectric resistivity is defined as the electrical resistance offered per unit length and unit cross-sectional area at a specific temperature and is denoted by ρ. Electrical resistance is also known as specific electrical …
WebAug 3, 2024 · Symbol of specific resistance is the same as resistivity and that is ρ. And also the SI unit of specific resistance is ohm – meters which is the same as the unit of resistivity.
