Un generator electric de curent continuu debitează în circuitul exterior aceeași putere P = 4 W dacă, la borne, se conectează un rezistor R1 = 0,01 Ω sau un rezistor R2 = 100 Ω. Determină: valoarea rezistenței interne a generatorului; randamentul circuitului, dacă la borne este cuplat, în locul rezistorilor anteriori, un alt rezistor cu rezistența electrică R3 = 2 Ω; energia electrică disipată pe rezistorul R3, în condițiile punctului b, timp de o oră; valoarea maximă a puterii pe care sursa o poate debita în circuitul exterior, dacă rezistența acestuia are o valoare convenabil aleasă.
