Question: My 6th grader wants to determine which wire has the most current in a circuit for her science fair project because she picked the question, “Which wire conducts the most electricity”? She picked that because my husband is an electrician but we can’t figure out how to test this at her level. This is her project, we can help but it’s hers. any ideas?
Answer: We suggest using the Compact Digital Multimeter to test the strength of the current coming from a wire. It is inexpensive and will give her a digital readout of the amount of current in a circuit.
