You change the speed of rotation.
You step down voltage from an AC generator with a transformer.You step down frequency from an AC generator with a motor/generator set, or with an inverter. This is not a common thing to do.
An electrosurgical generator is a piece of medical equipment. The generator takes mains AC current and turns it into radio frequency (>100Khz) AC current. This current can then be used to cause a tissue effect in a patient (i.e. cutting, coagulation, fulguration).
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
Alternator and ac generator is equal
The frequency in Hz is governed by the speed of a generator. The voltage is governed by the winding and types of connections of these windings.

It's speed and the number of poles.

Adverbs of degree modify adjectives to indicate a greater or lesser extent or characteristic.Adverbs of frequency and time modify adjectives to tell when, or how often, the characteristic is applicable.Examples:He is very tall. (degree)She was extremely sad. (degree)The banker is usually punctual. (frequency)The food is always delicious. (frequency)The generator was previously functional. (time)
what is the construction of ac generator
Modify it - to do what? Please restate the question.
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
Alternator and ac generator is equal
NO, generator always generating AC current,when commutator is used,at that time AC is converted in DC.and due to this generator is called dc generator.
DC generator
Ac current. Ac current is easily controlled for voltage and frequency. The diesel engine runs a generator that generates AC current for use in the electric drive motors on each drive wheel.
The frequency in Hz is governed by the speed of a generator. The voltage is governed by the winding and types of connections of these windings.
