The power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power ...

Before we go forward and run some of the tests that we are going to see hereinafter, let us check a few of the symptoms to understand if those tests are worth doing. We have mentioned some symptoms ...

How accuracy is defined in DC programmable power supplies How and why the power supply experiences voltage output errors How to wire test leads and sense leads for accurate measurements When testing ...

A power supply’s output capacitors - which are typically ceramic capacitors with values between 100nF and 100μF - cost money, take up space, and, in the case of delivery bottlenecks, can be difficult ...

One application that uses a precision power supply and DMM involves characterizing the current drawn by a device or circuit board at different voltage levels. Figure 1 shows a typical setup. Engineers ...
