... For example, a 2 Ω component has a greater resistance than a 1 Ω component, and will reduce the flow of charge through it more effectively. The resistance increases when you add more components in series. For example, the resistance of two lamps is greater than the resistance of one lamp, so less cu ...

... One advantage to the use of AC voltage is its ability to be stepped up to a higher value or stepped down to a lower value. AC can then be transmitted over great distances at higher voltage and lower current to avoid energy losses and then stepped down to the 120 - 240 volts we use in households. Th ...

... At the junction of the p-type and n-type some of the electrons will migrate from the ntype into the holes in the p-type. This creates a region at the junction without any charge carriers i.e. an insulating layer. As electrons have left the n-type it becomes positively charged near the junction whil ...

Nanogenerator
Nanogenerator is a technology that converts mechanical/thermal energy as produced by small-scale physical change into electricity. Nanogenerator has three typical approaches: piezoelectric, triboelectric, and pyroelectric nanogenerators. Both the piezoelectric and triboelectric nanogenerators can convert the mechanical energy into electricity. However, the pyroelectric nanogenerators can be used to harvest thermal energy from a time-dependent temperature fluctuation.
