Circuit Project Electronic

In sometimes when friends want to modify negative voltage source from the outside is positive voltage. We try to come to see this circuit use op-amp IC LM741, be usable easily and, It can change R1,R2 for fix the expansion ratio has of the circuit with. See the detail in the [...]

If you want positive voltage regulator 9Volt. I sizes beg for to suggest the nine s wander this , because it easy is good, the equipment is , seek easy with see the circuit has already. Friends must appear familiar certainly. It uses transistor ordinary just this , [...]
