Question: A 1.40 ohm resistor is connected across a 9.00-V battery. The voltage between the terminals of the battery is observed to be only 8.00 V. Find the internal resistance of the battery. Make sure the answer is in Ohms.© BrainMass Inc. brainmass.com December 24, 2021, 4:53 pm ad1c9bdddf
Real batteries have resistances inside them. We can model this simply as a battery providing an ideal electro-motive force (9.00 V in this case) in series with the internal resistance, Ri.
In this case, a load is connected to the ...
