The measure of electrical resistance in ohms is indicated by which symbol?

The measure of electrical resistance in ohms is indicated by the symbol "R." This is a standard notation used in electrical engineering and physics. Resistance quantifies how much an object opposes the flow of electric current, and its unit of measure is ohms (Ω).

In contrast, the other symbols represent different electrical concepts: "V" denotes voltage (the electrical potential difference), "I" stands for current (the flow of electric charge), and "E" can be used to represent electromotive force (EMF). Each of these quantities plays a crucial role in understanding electrical circuits, but "R" specifically refers to resistance.
