1.Rolul generatorului electric într-un circuit electric este:
a) de a închide circuitul;
b) de a produce sarcini electrice;
c) de a menţine constantă diferenţa de potenţial dintre bornele circuitului;
d) de a împiedica mişcarea ordonată a purtătorilor de sarcină electrică liberi într-un circuit electric.

b) to produce electrical charges;

Explanation:

Electrical generators are used in a circuit to produce electrical charges. The flow of these charges actually produces electrical energy in a circuit which is needed and essential to power devices and gadgets.

A generator uses mechanical energy through the movement of its parts to produce electrical energy. The flow of electrons streams produces the electrical energy which helps to produce power.

A generator works on the basis of electromagnetic induction using the movement of electric charges.
