The big mal near Sally and Amy's city has extended their operating hoursto accommodate the huge crowds expected for the After Thanksgiving Sale. In their eagerness to beat the crowd, Sally forgets to turn off the headlights when she gets out of the car at the mall parking lot. The headights in her car require 45.0 w of power each, and her 12.0 V car battery is rated at 92.0 A-h. When the two friends come back to the car after a long and successful shopping spree, they find that the car refuses to start as the battery is now completely discharged. How long were they in the mal? Assume that they come out just as the battery dies.

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.
