When running on its 11.5V battery, a laptop computer uses 7.5W. The computer can run on battery power for 9.0 h before the battery is depleted.(a) What is the current delivered by the battery to the computer?(b) How much energy, in joules, is this battery capable of supplying?(c) How high off the ground could a 75 kg person be raised using the energy from this 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.
