A battery has voltage when it is electrically charged, and ready to do electrical work. This is similar to water pressure in a water system. When the water tower is full, it has pressure (voltage)…

Literally memorizing the muscles, bones, arteries and veins in a desperate attempt to pass the test, and hopefully retain enough memorization to make it through the state boards. Now skin physiology was another thing – that just made sense – and knowing why we needed to know…
