An electric heater has a power rating of 500W when connected to a given voltage V. If two of these heaters are connected in series to the same voltage, is the power consumed by the two heaters greater than, less than, or equal to 1000W? Explain.
-when the two heaters are connected in series, the equivalent resistance increases to 2R
-the heaters are connected to the same potential difference, however, and therefore they draw half the original current
-from P = I^2R, we can see that each heater now dissipates one quarter the power of the single heater, for a total power consumption of one-half the original value
