Hello, first time user here. I have a couple of questions I am just unable to find the answers to. I am sure there are smarter people than me on here that may be able to help me out. Thank you in advance if you can.
1. About what is the operating frequency of a normally loaded switching power supply?
2. In a TTL circuit, what is represented by 1.5V?
Which instrument must always be used with the power off in a circuit under test, a voltmeter, ohmmeter, ammeter or frequency counter.
Again, thank you if you can help
