A smoke detector operates on a 9 V battery having charge capacity of 4500 mA h.
(a) If the battery needs to be changed approximately every 2 years, how much power does the smoke detector consume on average?
(b) Assuming that the battery can be recharged through a charger providing 0.5 A current, how long would it take to fully charge the battery?

Suppose an alkaline 9 V battery can supply 100 mA (to power a small light bulb, for example) for about 4 hours before too much of the voltage is depleted to be of use. It is therefore described as having a capacity of 400 mAh (milliamp-hours). How many electrons is this? Use the same charge for the electron as before. Also, where do the electrons come from and where do they go?

1. A battery with a capacity of 2500 mAh (milliamp-hours) is used to power a device that constantly draws 400 mA of current. Assuming that the battery is ideal, how long will the battery last? The same battery as above is now used to power a clock that only draws current when the second hand "ticks". The current draw during this movement is 2mA. A clock ticks every second but note that the second hand doesn't take a second to...

Joe Bruin owns a Nissan Leaf electric car, but he wants to make the car even more “green” by installing solar cells on top of his electric car. Plus, in the event of a zombie apocalypse, Joe would like to be able to use his solar car to escape the zombies even after the electricity grid goes down. Joe’s car weighs 3500 lbs, and when the sun is shining overhead, the solar cells generate a total of 1000 watts of...
