When I used Multisim to simulate the op amp circuit before, I found that the op amp output was greater than the power rail. Sometimes I wanted to use the op amp as a comparator for open-loop simulatio...
I am planning to buy a multimeter. Most of the use scenarios require testing voltages of 600-900V (occasionally overvoltages of 1000+), so I have been using Fluke's 15B+. The meters in the company are...
