Which answer contain protective devices?

• fuse , RCD , circut breaker

• fuse , DC engine , transformer

• RCD , fuse , ammeter

How fuse work?

• it works on principe of magnetic induction

• It melt and make gap in the circut

• it change parameters of voldage

• in change energy from mechanical into electrical

what does shaft do?

• generate magnetic flux

• it cools down windings

• it connect's turbine and generator

Why it is necessary to protect circuts?

• because in don't protected circuts there is a risk of getting allectro shocked?

• because rotating speed depends on frequency

• because engines are generating power

• Słowacki was a great poet

where are generators placed?

• in a transmision system

• in a household

• in a power palnt

• in a transformer station

what are important parts of generator?

• fuse , stator , rotor

• rotor , stator , shaft

• bearing , stator , transformer

• stator , rotor , magnetic flux
