What does R equal?

Explanation:
R represents resistance in an electrical circuit. Resistance is measured in the ohm, with the symbol Ω, so R equals resistance expressed in ohms. This fits Ohm’s Law, V = I R, where R is the ratio of voltage to current and is quantified in ohms. The other terms correspond to different quantities: voltage is denoted by V, capacitance by C, and inductance by L, so they don’t describe R.
