Re: [Electrical] Multimeter question

Keep in mind that sticking two electrodes in a potato creates a mini-battery if the composition of the metals is different. Before taking a measurement make sure that the voltage measured after sticking in the electrodes is 0, otherwise your results will be seriously skewed. If the voltage is not 0, try using something else as electrodes - such as two identical stainless steel forks.

I thought about that but wasn't sure the OP would understand. It would certainly add to the science project.

EDIT: example
