1. ### What equpment can be used to time a quick blow fuse

Hi, You can just connect a scope across the fuse. Observe the I/t graph on the scope and when the fuse blows the current on the scope will drop to zero. Just calculte how how it was before the current went to zero.
2. ### Time and Thermal Time constant explaination

Hi, I have read the defination of a time constant on the internet and yet still don't quite understand it. How do I relate it to the following sentece and what does it mean: " The transient energy will have a duration much shorter than the thermal time constant of a bridge wire." ANY...
3. ### Measuring Energy of Transients in electrical circuits

Hi, The source impedance varies from 50 to 200 ohms. The load is between 0.5-1.5 ohms. Using a scope would be quite a long procedure and not very accurate. ANY MORE HELP WOULD BE GREAT (ANYONE).
4. ### Measuring Energy of Transients in electrical circuits

Hi, Is there a way or reasonably priced equipment out there that can measure the energy levels of transients in electrical circuits? Any help would be appriciated!
