In circuit notation, which symbol represents resistance?

Explanation:
In circuit notation, resistance is represented by the symbol R. This is the value that links voltage and current in Ohm’s law, V = I R, where V is voltage, I is current, and R is the resistance. I stands for current, V for voltage, and E is often used for electromotive force in power sources; neither of those denotes resistance. When you label a resistor or its value, the quantity to denote resistance is shown as R (measured in ohms).
