Use the formula: Power (P) = Voltage (V) × Current (I). Rearrange the formula to find resistance (R): R = P / I^2. Calculate the current (I) using the charge (Q) and time (t): I = Q / t. Substitute values into the formulas to find the resistance. Resistance (R) = 1 ohm.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
