Question

Given the size, shape and material of a conductor, what else would you need in order to find the current through the conductor?

Answer 1

Explanation:

The number of charges flowing per second inside the conductor is called the current through the conductor. Mathematically, it is given by :

$I=\dfrac{Q}{t}$

Where

Q is the charge

t is time

Since, Q = ne

n is number of electrons

e is the charge on one electron

So, to find the current through the conductor we must know the number of electrons moving per second through it. Hence, this is the required solution.
