A 11.45-V battery with internal resistance R1 = 0.1373 is said to be charged by a battery charger that is capable of delivering acurrent i= 9.7959 A. What is the minimum emf the battery charger must be able to supply in order to charger the battery.
Homework Answers
emf of charger= voltage across battery+ potential deop across
internal resistance
E= V+ I*R
=11.45 + 9.7959*0.1373
= 12.795 V

You have developed a new way to measure the internal resistance of a battery. The circuit you have created is shown below, with a non-ideal battery (EMF and internal resistance r in the red box), a constant external resistor R1-19.122, and a variable resistor R2. R2 has a resistance you can change over a wide range of values, from nearly zero to nearly infinity. In this circuit, you measure the voltage over R2, AV2. R1 is used to avoid damaging...
