Detailed explanation-1: -The unit of the electrical resistance, measured with direct current, is the ohm (abbreviated ), named after the German physicist and mathematician Georg Simon Ohm (1789-1854). According to ohm’s law, the resistance R is the ratio of the voltage U across a conductor and the current I flowing through it: R = U / I.
Detailed explanation-2: -The SI unit of electric resistance is the ohm ().
Detailed explanation-3: -Resistance is defined as the voltage developed across the resistor per ampere of current through the resistor. Resistance has a symbol of R measured in unit called Ohm which has a symbol .
Detailed explanation-4: -Resistance is the opposition that a substance offers to the flow of electric current . It is represented by the uppercase letter R. The standard unit of resistance is ohm, sometimes written out as a word, and sometimes symbolized by the uppercase Greek letter omega. (symbol: )
Detailed explanation-5: -R is the resistance of the resistor R in ohms () V is the voltage drop in the resistor in volts.
