В чем разница между PNP и NPN транзисторами? Я постарался просто на примере показать разницу в работе двух видов биполярных транзисторов. Я использовал светодиод(и резистор для защиты), для демонстрации ихней работы. В качестве примера я использовал pnp транзистор 2n2907 и pnp транзистор bc337. Регулировал напряжение на базе коллектора с помощью переменного резистора(потенциометра).
