Uses Of The Generator Effect (ht Only) (GCSE Physics)

Why are slip rings used on an AC generator while a commutator is used on a DC generator?

Why does increasing the number of turns on the coil in a generator increase the generated voltage?

Which action will increase the output voltage of a simple generator for the same magnet and coil geometry?

In an electric guitar pickup the generator effect is used to produce a signal when metal strings vibrate because the vibrating string changes what?

Why does increasing the magnetic field strength in a generator increase the induced emf for a given rate of rotation?

What is one environmental advantage of using large generators driven by renewable turbines (wind, hydro) rather than many small internal combustion engines to produce electricity?

A detector coil placed near a moving metal object can produce an output because eddy currents are induced. These eddy currents are a consequence of which effect?

What change will increase the induced emf in a coil according to Faraday’s law?

What is the primary reason that large-scale electricity generation uses rotating generators rather than static induction coils?

Which vehicle technology uses the generator effect to recover kinetic energy and convert it back into electrical energy during braking?

Which device converts mechanical energy to electrical energy using the generator effect and then supplies alternating current directly to a power grid?
