The role of water in the living organism has not changed since life’s first creation in salt water billions of years ago. The human body is 75% water, while the brain alone is comprised of 85% water. The blood, consisting of 92% water, carries oxygen and essential nutrients to capillaries where they are released into a water-based fluid…

Resistance in a Wire

What is resistance? A potential difference (V) applied across a wire of length (l), there is in the conductor, an electric field (E). In this electric field the free electrons are not however under continuous acceleration (Ee/m). This is because they repeatedly collide with the moderately massive vibrating atoms losing their kinetic energy. The vibrating atoms having gained this kinetic energy now vibrate more. The resulting increase in the average vibration kinetic energy is rise in temperature. Movement of charge…
