To solve this question, you must calculate the maximum voltage that can be applied before its power rating is exceeded. Use the formula P x R = E^2. For the 500-ohm resistor, 2 x 500 = 1000. The square root of 1000 gives the maximum voltage of 31.6 volts. For the 1500-ohm resistor, 1 x 1500 = 1500. The square root of 1500 gives a maximum voltage of 38.72. So the 31.6 V for the 500-ohm resistor limits the voltage value. ANSWER 31.6 volts
