The team measured the electrical charge and contact areas created by water droplets spreading and contracting on a flat plate of Teflon – effectively simulating the movement of droplets over the ...
The film explains the measurement of electric current using ammeters, which quantify the flow of elementary charges in a circuit. It introduces the concept of amperes as a measure of the number of ...
Researchers have discovered that water generates an electrical charge up to 10 times greater than previously understood when it moves across a surface. The team observed when a water droplet became ...
