Answer:
Number of electrons,
Explanation:
A strong lightning bolt transfers an electric charge of about 16 C to Earth, q = 16 C
We need to find the number of electrons that transferred. Let there are n electrons transferred. It is given by using quantization of electric charge as :
q = ne
e is elemental charge
So, there are electrons that gets transferred. Hence, this is the required solution.
The resistance of a conductor is given by
where L is the length of the wire,
the resistivity of the material and A the cross-sectional area.
We can see that if all the other quantities do not change, if the new length of the conductor is 4 times the original length:
, then the new resistance is also 4 times the original value:
where L is the length of the wire,
We can see that if all the other quantities do not change, if the new length of the conductor is 4 times the original length:
