Satellites have managed to detect faint electromagnetic signals generated by ocean tides, suggesting that space-born sensors ...

Extracting lithium from brine requires you to wait for the water to slowly evaporate, you cannot control how fast you produce ...

Electric propulsion is being increasingly used on space missions and could ultimately replace thrusters using chemical ...

An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens. The wire just gets very hot and the battery loses stored internal energy – it ...

If you think about it, that isn’t such a strange question. We talk about electrical current — just like current in a stream. Many introductory books on electricity try to relate voltage to ...

How? By sending an electric current through the spoon to your tongue. It sounds absurd. So, naturally, I had to try it out. Kirin is a Japanese company that currently sells the Electric Salt Spoon ...

Sense resistors are used to measure how much current is passing through the MOSFETs (and therefore the load), the MCP4921 Digital to Analog Converter (DAC) from microchip is used to set the curren ...
