A cell phone battery is rated at 3.85 V and can store 10.78 watt-hours of energy. (a) How much average current can it deliver over a period of 3 hours if it is fully discharged at the end of that time? (b) How much average power is delivered in part (a)? (c) What is the ampere-hour rating of the battery?
Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
