A coil in a generator rotates more rapidly. What happens to the amplitude and frequency of the output voltage?

In a magnetic braking system, how is energy dissipated?

An ideal transformer has 400 turns on the primary and 100 on the secondary. If the primary is connected to 240 V AC, what is the current ratio I_secondary / I_primary (neglecting losses)?

Which change would increase the energy stored in an inductor the most?

A capacitor and inductor in series are connected to an AC source. At resonance:
