Experiment 13: Op-Amp / Controlled Voltage Source
... Ideal operational amplifier approximation assumes that op-amp input currents are negligible and can be ignored. The op-amp’s input resistance is assumed to be infinite and its output resistance is assumed to be zero. The op-amp can be modeled as a voltage controlled voltage source whose output volta ...

3 Ohm’s Law Experiment 3.1
... all (i.e. 0.00), you have a very small current and can then move the cable to the 400 mA plug. An ammeter must be connected in series with the circuit element of interest, as shown in Fig. 3.4(b). This means that unlike measuring voltage, if you want to measure current you must break the circuit and ...

Contact resistance and TLM measurements
... In measuring resistance with the four-point-probe or van der Pauw methods, we used 4 contacts (2 for current, 2 for voltage) to determine the sheet resistance of a layer while minimizing effects of contact resistance. However, in transistors and other electronic devices, the contacts are a necessary ...
