A team of electrical engineers wants a new smart phone’s battery to last for 12 hours. If the smart phone has an average appliance load of 2.6 watts, what does the battery capacity need to be, in amp hours? Express your answer as a decimal to the nearest hundredth. 5.2 The charging time t, in hours, of a phone with battery capacity c, in amp hours, can be calculated using the equation t = 2c. If Jared’s new phone has a battery capacity of 3.72 Ah, how many hours will it take his phone to fully charge? Express your answer as a decimal to the nearest tenth. 5.3 Marnie buys a smart phone from a different company. She heard that this phone takes only 4 hours to charge. Assuming Marnie’s smart phone has an average appliance load of 2.6 watts, how many hours can Marnie expect to use her phone before the battery dies? Express your answer as a decimal to the nearest tenth.
