Two toys both use 2 D cell batteries in series. This means that they both require 3 volts to operate. The toys are left on and toy 1 stops working after 2 hours while toy 2 stops working after 4 hours. Which toy uses energy more quickly? Which toy has a larger power rating? Which toy draws a greater current? Which toy has a lower resistance? (Assume the D cells are initially identical.) Write an equation for power in terms of voltage and resistance.
