Question

Homework 1 A rechargeable flashlight battery is capable of delivering 105 mA for about 15 h. How much charge can it release at that rate? If its terminals voltage is 1.1 V, how much energy can the battery deliver? I. 2. The current entering the positive terminal of a device is )- A and the voltage across the device is v)-5dildr V (a) Find the charge delivered to the device between t-0 and (b) Calculate the power absorbed. (c) Determine the energy absorbed in 5 s 4s 3. A 2.8-k W electric heater takes 20 min to boil a quantity of water. If this is done once a day and power costs 12 cents per k Wh, what is the cost of its operation for 30 days?
