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 ...

You often need to measure currentduring circuit design and debugging.You can perform that task bybreaking a path, inserting a shunt resistor,measuring its voltage, and convertingthe voltage to current ...

Measuring dynamic currents with an oscilloscope is challenging, but this updated differential current probe makes it simple ...

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 ...

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 ...
