A strong lightning bolt transfers 30C to Earth. How many electrons are transferred? - Sri Chaitanya Infinity Learn Best Online Courses for NCERT Solutions, CBSE, ICSE, JEE, NEET, Olympiad and Class 6 to 12

A
18.75× $10^{19}$
B
10 $.$ 75× $10^{19}$
C
19 $.$ 75× $10^{19}$
D
None of these

Solution:

Concept: An attribute of matter is charge, which is also represented as current. Lightning consists of current. Lightning strikes and charges are transmitted to the earth as current flows.. The charge constitutes electrons. Using the unitary method and dividing the total charge by the charge of electrons, we can calculate the number of electrons.
We know that 1e=1.6×

10^{- 19}

C
A material's ability to experience a force in an external electric field is known as charge. Positive and negative charges are the two different sorts of charges. Also, current constitutes charge.Positive and negative charges are the two different sorts of charges. and positive charge. Most often, charge is the movement of negatively charged electrons.The electron has a charge of-
1e=1.6×

10^{- 19}

C
Lightning is developed when the static electricity between the clouds makes one cloud to be positively charged and the other cloud to be negatively charged, hence current flows between them.
Given, a lightning bolt strikes the ground, it consists of 30C. The number of electrons transferred to the ground from the lightning is the number of electrons that are present in 30C charge.
Using the unitary method, the number of electrons can be calculated as-
1e=1.6×

10^{- 19}

C
⇒xe=

\frac{30 C}{1.6 \times 10^{- 19} C}

⇒x=18.75×

10^{19}

The number of electrons are 18.75×

10^{19}

Therefore, the number of electrons transferred from 30Cto the ground is 18.75×

10^{19}

Hence, the correct option is 1.
