An industrial gas-turbine ignition system uses a high-voltage spark to ignite fuel. The system consists of:
Microwave signals are electromagnetic waves. State two properties that are common to all electromagnetic waves.
Which of these electromagnetic radiations has a wavelength shorter than visible light?
The transformer supplies an output voltage of 5500 V5500\text{ V}5500 V a.c. to the ignition system. 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 electrode is supported by ceramic collars inside the grounded metal casing.
