... Power is lost to heat as electrons encounter resistance to their flow through the conductor. A kettle at 120V causes 12.5 Amps to flow through the heating element that has a resistance of 9.6 Ohms. Power consumed is 120 x 12.5 = 1500 Watts. If it takes 6 minutes (0.1 hr) to boil the water, and the p ...

Buck converter
A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
