The provided chart is an Ohm's Law and Power Wheel, which organizes formulas based on the quantity being calculated. The bottom-right quadrant is explicitly labeled 'R' and contains the three standard formulas for calculating resistance when other values (Voltage 'E', Current 'I', or Power 'P') are known: R = E / I R = E² / P R = P / I² Therefore, this is the correct section for calculating values expressed in Ohms.

demonstrates the application of the formula R = V/I (where V is equivalent to E) to calculate

resistance in Ohms.

R as the ratio of voltage E to current I (R = E/I).

between voltage, current, and resistance as defined by Ohm's Law, which is the basis for the

calculations in the specified quadrant.
