Multiple Choice
Lithium polymer batteries have revolutionized the battery field due to their light weight,high energy density (about four times greater than nickel-cadmium or nickel-metal-hydride cells) and low internal resistance.At 25 C a three cell lithium polymer battery has no load voltage of 11.1 V and an internal resistance of 300 m .If the battery is used to power a device that needs a minimum of 10.0 V,e.g.,it will not work if the applied voltage is below 10.0 V,what is the minimum resistance of that device?
A) 1.35
B) 2.43
C) 2.73
D) 3.03
E) 4.62
