The viscosity of a fluid can be measured by a device called the viscometer, which is an instrument that estimates a fluid's thickness, internal friction, and resistance to flow. There are many types of viscometers, perhaps the most basic one is the U-tube viscometer, which is used to mea...
Power is measured in watts, named for Scottish inventor James Watt. Wattage is a measurement of heat generation. Any time energy is transferred,heat is generated, and the faster it transfers, the more heat is created. An easy way to visualize this interaction is with your hands. When you'...
Heat produced in a resistor Power P = I V or I 2 R Power is measured in Watts = amps volts All wire is rated for the maximum current that it can handle based on how hot it can get To carry more current you need wire of a larger diameter this is called...
Velocity is defined as avectormeasurement of the rate and direction of motion. Put simply, velocity is the speed at which something moves in one direction. The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity...
