An ultra-low power sensor operates using energy harvesting from various sources for efficient monitoring. The oscillator ...

You can investigate voltage across cells and lamps in a series and parallel circuit by connecting the following circuits. Put one voltmeter in position V 1 and record the reading in a suitable table.

are electronic components that can be used to regulate the voltage in circuits and to make logic gates. Light-emitting diodes (LEDs) give off light and are often used for indicator lights in ...
