Differences between Lightning Electricity and Thunder in Physics

 Here are the differences between Lightning Electricity and Thunder. 

Aspect	Lightning	Electricity	Thunder
Nature	A natural electrical discharge in the atmosphere.	The flow and presence of electric charge.	The sound produced by the rapid expansion of air following a lightning strike.
Type of Energy	Electrical and thermal energy.	Electrical energy.	Acoustic energy (sound).
Cause	Caused by the buildup and discharge of electrical charges in a thunderstorm.	Generated by various means such as chemical reactions, solar panels, or generators.	Caused by the discharge of lightning, leading to rapid heating and expansion of air.
Speed	The return stroke of lightning can travel at 1/3 the speed of light.	Depends on the medium; near the speed of light in a vacuum.	Sound of thunder travels at the speed of sound, approximately 343 m/s.
Temperature	Can heat the air to about 30,000°C.	Does not typically involve high temperatures unless there is a fault.	Does not involve temperature; it's a sound wave.
Measurement	Not typically measured since it's a natural event.	Measured in amperes, volts, and ohms.	Measured in decibels (dB).
Danger	Can cause fires, property damage, and fatalities.	Can be dangerous but is generally safe with proper insulation and safety measures.	Not harmful itself, but indicates proximity to lightning.
