Area of two elements comes together when relative motion occurs between the elements to form a lower pair e.g nut and screw, universal joint used to connect two … Read more
Volt and ampere are two measures of electrical current or flow of electrons. They define characteristics of an electricity supply. Voltage is a measure of the pressure that allows electrons to flow while ampere is a measure of the volume of electrons. These measurements of supply allow us to calculate the power a supply can … Read more
