unwanted rush currents same like in the aircrafts all the
grounding wires of electrical appliances in the plane ware
connected to neg terminal of the battery hence the lekage
current will flow through this neg terminal

Answer / partha mandal

a electronegative charge is created in the air craft, and all the earth terminals are made connected to it to eliminate the leakage voltage. An earthing means neutralizing the leakage voltage not the returning path.

Answer / pradeep

due to the friction between the air and aeroplane mettalic
body the surrounding of aeroplane become the conductive this

as erthing in aeroplane

Answer / sailesh ranjan patel
