Some of the books I have state that power comes from the negative terminal on the power supply.If that is the case, the circuit starts from the negative right? Say I have a simple circuit with a 6v ...
I posted a more vague version of this question a few days ago here and this question was linked as being similar. Answers in both threads were extremely helpful and were along the lines I was ...
One would be inclined to think the average current on resistor R would be exactly the same as in the load L, but I'm not so sure of that fact, due to the effect of the (big, 1000uF+) capacitors. ...
I'm using a repurposed ATX power supply for my hobby projects since it's got 3.3/±5/±12 outputs, all of which are really convenient. But one thing I didn't really think about until I slipped my probes ...
(Apologies in advance if this question is out of scope of this stackexchange but I wasn't really sure where else to post it. Any help, advice, useful links would be really appreciated though) I have ...
Possible Duplicate: Choosing power supply, how to get the voltage and current ratings? I have a 5V / 1A regulated supply. I'm thinking of using it to power a PCB which asks for 5V and ...
We have some big resistor test loads, like 8 Ω 250 W loads for simulating speakers: Are there also big variable load resistors for testing power supplies? What are they called? If not, what do ...
