You have designed an op-amp circuit to measure a small voltage. The circuit gain is -10V/V, but it appears that the input impedance to the circuit is effecting the device as it is being measured. How ...

Temperature is by far the most commonly measured physical parameter. With so many new ideas for connected devices in the works for consumer and industrial applications, you often need high-accuracy ...

Every electrician has been there: You open a panel, and nothing is marked — or the markings are so outdated, you don’t have confidence in their accuracy. In some ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

Sometimes, it's necessary to make microvolt measurements in the presence of volts. For example, the need arose to measure the thermoelectric potentials in an RTD circuit in which the 10 V applied to ...

Designs that need to measure small signals riding on high-voltage power rails suggest the use of isolation devices. However, a high-common-mode-voltage instrumentation amplifier used with a ...

Large circuit breakers in service today at industrial and commercial facilities come in many shapes, sizes, configurations, and voltage ratings — with the primary purpose of protecting electrical ...
