For example, 20 A is a bigger current than 5 A. The word ‘ampere’ is often abbreviated to ‘amp’, so people talk about how many amps flow. A device called an ammeter is used to measure current.

A power analyzer can be used to identify power guzzlers and provides valuable information for optimization by taking measurements under different operating conditions.

A device called an ammeter is used to measure current. Some types of ammeter have a pointer on a dial, but most modern ammeters have a digital display. To measure the current flowing through a ...

In particular, interest in non-contact metrology for measurement of different types of microelectromechanical-system (MEMS) devices has risen. Such metrology can help resolve MEMS fabrication ...

By improving the characteristics of the internal LED and photodiode arrays, the new device provides maximum switching times of 0.5ms (tON) and 0.2ms (tOFF). These higher switching speeds make the new ...
