An industrial ozone water-purification system is used to treat drinking water. The system consists of:
Ultraviolet radiation consists of electromagnetic waves. State two properties that are common to all electromagnetic waves.
Which of these electromagnetic radiations has a wavelength shorter than ultraviolet radiation?
The transformer supplies an output voltage of 4400 V4400\text{ V}4400 V a.c. to the discharge tube. The input voltage to the transformer is 110 V110\text{ V}110 V a.c.
Give the name of this type of transformer.
State the relationship between input (primary) voltage, output (secondary) voltage, primary turns, and secondary turns.
There are 80 turns80\text{ turns}80 turns on the primary coil. Calculate the number of turns on the secondary coil.
Suggest a reason why the high-voltage electrodes are supported by quartz glass insulators inside the steel chamber.
