battery voltages actual vs. expected

I am doing a lab with 1.5V battery as power source - I have three resistors in parallel and then in series- my question is why or how do I get multimeter DMM readings of 1.59 V or higher than 1.5V readings when I am only using a 1.5V battery- please explain in basic terms so I may understand

What you have here is a case of the idealized situation not matching reality. Batteries never have the exact voltage indicated in their rating. There is typically a range of voltages, around the batteries stated voltage, which the ...

Solution Summary

In this solution I explain why the voltage printed on a manufactured battery (i.e. 1.5 volts) differs a bit from the actual voltage measured from said battery using a multimeter.
