Making Electric Current with Magnets
The output voltage of a transformer depends on the input voltage of the current (entering/exiting) the transformer.
entering
High voltage must be (reduced/increased) for you to use electric current safely in your home.
reduced
Transformers are used to (raise/lower) the voltage in transmission lines and slo to (raise/lower) the voltage to the level of household currents.
rise, lower
The number of wire loops in the (primary/secondary) coil of a step-down transformer is less than the number of loops in the (primary/secondary) coil.
secondary, primary
The voltage in the (secondary/primary) coil of a step-up transformer is greater than the voltage in the (secondary/primary) coil.
secondary, primary
A transformer has (four/two) wire coils wrapped around a single iron core.
two
The high-voltage (direct/alternating) current is transmitted through transmission lines.
alternating
(Step-down/Step-up) transformers raise the voltage of the alternating current produced by the generators in electrical power plants.
Step-up
