The battery as we know it today was an invention of Italian chemist and physicist Alessandro Volta. He witnessed electricity splitting water into its constituent elements of oxygen and hydrogen and ...

A ‘hole’ arises due to a missing electron in the valence band, which normally participates in covalent bonding between atoms. The absence of an electron creates a local absence of a negative charge, ...

It is common for Internet of Things (IoT) devices, industrial sensors, meters, precision, and medical equipment to require both a positive and negative voltage. Often, these voltages must be ...

This power-management tip introduces the two different circuits for a positive-to-negative voltage conversion and a negative-to-positive voltage conversion. However, there are times when a voltage ...
