Papers 1 and 2

I know that a voltage is induced in a conductor or a coil when it moves through a magnetic field, or when a magnetic field through it changes, and I can describe the factors that affect the size of the induced voltage.
I can describe how electricity is generated by rotating a magnet inside a coil of wire, and by rotating a coil of wire inside a magnetic field, and describe the factors that affect the size of the induced voltage.

I can describe the structure of a transformer, and I understand that a transformer changes the size of an alternating voltage by having different numbers of turns on its input and output sides.
I can explain how step-up and step-down transformers are used in the large-scale generation and transmission of electrical energy.
I know and can use the relationship between the input (primary) and output (secondary) voltages and the turns ratio of a transformer: input (primary) voltage / output (secondary) voltage = primary turns / secondary turns
I know and can use the relationship input power = output power, VₚIₚ = VₛIₛ, for 100% efficiency.
