Question

windmill shaft cannot be connected to the generator without a gear

Answer 1

It should be false.But still go through lecture once.

Answer 2

Windmill shaft cannot be connected to the generator without a gearbox because it is likely to affect the power generated and lessen this to a great extent. Moreover, when a gearbox is connected between the windmill shaft and the generator, the shaft RPM (revolutions per minute) is increased to an optimal value.
