Which symbol and unit of measurement are used for resistance? symbol: R: unit :
symbol: 0; unit: R
symbol: R: unit o
symbol: R: unit R

Unit of resistance is Ω (Omega).

Explanation:

The ability to measure the oppose the flow of electric current is called resistance of a circuit. Its relation with voltage and current is given by Ohm's law as follows :

V = IR

R is resistance

Its unit is Omega and it is represented by Ω.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

there are two significant figures.
