They are all ways you can make oscilloscope probes that measure current. If you think of a scope as a voltage measurement device, you ought to watch the recent video from Keysight Technology (see ...

The oscilloscope photo below shows this changing voltage. This method is good for a rough estimate. I’ll talk about doing more precise measurements when I talk about high voltage probes further ...

High Voltage A probe used to measure high voltage signals. Magnetic Magnetic probes sense magnetic fields in solenoid operated devices, stepper switches, relays, valves & coils. Optical Optical probes ...
