Question

a dc motor is a type of : a. pneumatic actuators b. hydraulic actuators c. electrical actuators d. mechanical actuator

Answer 1

answer :- (c) electrical acutators .

explanation :- $\textbf{electrical acutators are powered by}\\\textbf{ motor that converts electrical }\\\textbf{energy to mechanical torque.}$
and you know DC motor is the appliance that comverts direct electric current to mechanical energy. that's why DC motor is type of electrical acutators.

Answer 2

According to the data mentioned in the question that,

A DC motor is a type of;

The correct answer of this question is options C, electric actuators.

Because,by the definition of the electric actuators we came to know that electric actuators are powered by electricity to produce mechanical torque.

And similarly a DC motor converts electrical energy into the kinetic or mechanical energy.

That's why option C is the correct answer of this question.
