i had a question that is confusing me
if u had an adapter which gives 1.5,3,4.5,6,7.5,9,12 volt using a switch
when u move the switch let's say to 3v and measure it with voltmeter it gives 5.5v and when i move the switch to give 12v and measure it with voltmeter it gives 18.5 volt
i read on a site that u only get this voltage at full load so if the adapter is 12 1A
u must use all of the 1A to get 12v out put
and here comes the question let's say i am making a digital clock circuit and in the schematic it says use 5.5 let's say 6v how to get this value from the adapter as when i move the switch to 6v i will get may be 8.5v output as the clock will not consume all of 1A adapter and so making it at full load
also for this example of circuit types u can't calculate exactly the ampere needed to use adapter of the exact value
so how can i get the right value
