Adc generator is the same as a(n)
a. electric motor.
b. ac generator.
c. armature.
d. electric current.

b. ac generator.

Explanation:

DC generator is same as an AC generator because here both are used to produce power.

Both have coil which is being rotated between strong magnets. The main difference between them is slip rings which is  causing the direction change in AC generator due to which it will give constantly direction changing EMF. While in DC generator the the slip ring is in such a way that will not change the direction of EMF and we will get the EMF in same direction always.

SO AC generator is same as that of DC generator as both are used to generate potential difference
