Explanation
Electrical resistance is measured in ohms, named after Georg Simon Ohm. Resistance describes how much a material opposes the flow of electric current, as summarized in Ohm’s Law (V = IR). Materials like copper have low resistance, which is why they are used in electrical wiring. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
