| Measuring the current drawn by an apparatus is always a rather complicated matter. If a shunt resistor is placed across the positive supp...
| The capacity of a fully charged NiCd (nickel-cadmium) battery can be measured fairly accurately by draining the battery with a fixed curre...
| Temperature may be measured electronically with cornmercially available temperature- to-voltage converters. Since good-quality, calibrated...
| This little circuit converts temperature measured by an NTC (negative temperature co-efflcient) resistor inta a digital signal. The resis...
| Whereas over the past few centuries temperature was measured by observing the expansion of a liquid (and later, a solid), nowadays many te...
| Most simple and inexpensive frequency meters have a maximum input frequency of 10 MHz or 100 MHz. Decimal prescalers that enable frequenci...
| With circuit values as shown, this charger allows up to seven series-connected NiCd batteries to be charged. This number may be increased...
| Although it is almost impossible to imagine present-day meteorology without electronic equipment, sunshine is still widely measured with t...
