Which symbol and unit of measurement are used for resistance? symbol: r; unit : symbol: ; unit: r symbol: r; unit: o symbol: r; unit: r

Symbol: R,  Unit : ohm(Ω)

Explanation: Resistance of an object is the measure of its opposition to the flow of current. According to Ohm's law the electric current which will flow through a conductor is directly proportional to the voltage applied to it.

V = potential

I = current

R = resistance

The standard unit of electric resistance is ohm which is designated bu the symbol Ω. Ohm is defined as volt per ampere.

The correct answer is:

A. Symbol: R; Unit: Ω

The symbol and unit of measurement are used for resistance.
