At the Fermi National Accelerator Laboratory (Fermilab) in Illinois, protons are accelerated around a ring 2 km in radius to speeds that approach that of light The energy for this is stored in capacitors the size of a house. When these capacitors are being charged, they make a very loud creaking sound. What is the origin of this sound?

Step-by-Step Solution

Solution 1

At the Fermi National Accelerator Laboratory large capacitors are used to store the energy. These capacitors are subjected to strong electric field when these are in charging condition. This strong electric field causes to dielectric breakdown (the dielectric strength of air is) and dielectric (air) becomes as conductor. Due to this conduction and electric break down sparks with sound are produced.

Therefore we can hear the sounds in large capacitors when they are in charging condition.
