Detailed explanation-1: -What quantity of excess electrons is carried by the lightning bolt? Multiply the charge in Coulombs (10 C) by the conversion factor: (1 electron) / (1.6 x 10-19 C). The units of C cancel; the answer is in electrons. 9.
Detailed explanation-2: -Number of electrons in 10C charge is 101.6×10−19=6.25×1019. Q. Calculate the number of electrons constituting one coulomb of charge.
Detailed explanation-3: -6.25× excess electrons are in a typical lightning bolt.
Detailed explanation-4: -The charge of each electron, e=1.6×10−19C. ∴ Work done w=Vq=10−3×80=0.08J.
Detailed explanation-5: -Detailed Solution n t = 1 1.6 × 10 − 19 = 0.625 × ( 10 19 ) . The National Thermal Power Corporation (NTPC) will release the official notification for the NTPC Diploma Trainee 2023 soon.
