Q:
I was discussing physics in a general way with my daughter who is studying Engineering and the term culombs popped out of my mouth.I took high school physics 45 years ago and now, time and disuse has left me wondering what this term means I remember it was a measurement of energy or light. Maybe I am completely wrong. Can you jolt my memory and help me out? Thank you.
