The optimal resistance for maximizing battery terminal voltage is determined by the relationship between the internal resistance (r) of the battery and the external resistance (R) connected across its terminals. The correct answer to the problem posed is R = 4r, which ensures that the terminal voltage reaches its maximum value. This conclusion is derived from the equation V = IR, where the total resistance in the circuit is the sum of the internal and external resistances. The analysis confirms that matching the external resistance to four times the internal resistance optimizes voltage output.
