Question

Which alternator has the least speed:
(A) alternator coupled with hydraulic
turbine
(B) alternator coupled with steam engine
(C) alternator coupled with steam turbine
(D) None of the above​

Answer 1

An alternator coupled with hydraulic turbine has the least speed.

Explanation:

An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current.

Hydraulic Turbine is a device that converts the energy in a stream of fluid into mechanical energy by passing the extreme through a system of fixed and moving blades and causing the wheel to rotate.

An alternator coupled to a steam engine/turbine runs faster compared to an alternator coupled to a hydraulic turbine.

An alternator coupled to a hydraulic turbine runs at slow speed as compared to others.

Option A is the answer.
