Voltage is one of those ubiquitous aspects of everyday life that tends to get overlooked. We readily flip switches to turn on lights or press buttons to activate appliances, all without giving it much of a second thought. Electricity is everywhere, and it has always been that way for the vast majority of us. But when you give yourself a moment to think, you might wonder about this fundamental that powers the entire world. It may seem a little abstract, but voltage is really as easy to understand as a bucket of water.
