I am doing an experiment for a lab and I am confused as to what they are asking.
They ask to measure the voltage across the battery, the voltage across a 68 Ω resistor and then the current flowing in the circuit. However when measuring both the voltages they only ask to do one step that only provides one voltage.
My question is, does the voltage across the battery change, or does it remain constant regardless of the number of resistors added in series. I am using two 1.5 volt batteries and am getting a reading of 3.093 v from my multimeter.
I know this sounds confusing, I am confused myself. please let me know if you can help!
