Because the potential difference ΔV is the same across the two bulbs and because the power delivered to a device is P = I(ΔV), the 60–W bulb with the higher power rating must carry the greater current. Because charge does not accumulate in the ...

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.
