Ask Physics Current Electricity ELECTROSTATICS

Can the frictional electricity produced during landing of a plane be used for constructive purposes?

As we know that in aeroplane during landing the charged produced in it due to the friction with ground are earthed through its wheels; can this charge be stored with the help of a capacitor and used for useful purpose? Answer: I feel that this is a metter for research. If you feel otherwise and […]
