A typical cell phone consumes an average of about 1.00 W ofelectrical power and operates on 3.80 V. (a) What average currentdoes the phone draw from its battery? (b) Calculate theenergy stored in a fully charged battery if the phone requirescharging after 5.00 hours of use.
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.
A typical cell phone consumes an average of about 1.00 W of
electrical power and operates on 3.80 V. (a) What average current
does the phone draw from its battery? (b) Calculate the
energy stored in a fully charged battery if the phone requires
charging after 5.00 hours of use.
