Selection Guide to Clamp-On Current Probes
Selection Guide to Clamp-On Current Probes

... Current probes may also have AC or DC voltage outputs to accommodate current measurements with instruments (loggers, scopes, etc.) with voltage ranges only (Figures 4 and 5). This is simply done by conditioning the current probe output inside the probe to provide voltage. In these cases, the probe m ...

... EMFs in parallel are not used to increase voltage but to provide more energy when large currents are needed. Each cell only produces a fraction of total current so loss due to internal resistance is less than for single cell. Batteries will last longer. In this case, VR = 12V and if R=1, IT = 12A w ...

Current mirror

A current mirror is a circuit designed to copy a current through one active device by controlling the current in another active device of a circuit, keeping the output current constant regardless of loading. The current being 'copied' can be, and sometimes is, a varying signal current. Conceptually, an ideal current mirror is simply an ideal inverting current amplifier that reverses the current direction as well or it is a current-controlled current source (CCCS). The current mirror is used to provide bias currents and active loads to circuits. It can also be used to model a more realistic current source (since ideal current sources don't exist).The circuit topology covered here is one that appears in many monolithic ICs. It is a Widlar mirror without an emitter degeneration resistor in the follower (output) transistor. This topology can only be done in an IC as the matching has to be extremely close and cannot be achieved with discretes.Another topology is the Wilson mirror. The Wilson mirror solves the Early effect voltage problem in his design.
