WebWe have seen that the charge that moves past a point on a resistor in a time is given by 𝑄 = 𝐼 𝑡. The charge that moves past a point on a resistor in a time is given by 𝑄 = 𝑒 × 𝑁, where 𝑒 is the charge of an electron and 𝑁 is the number of electrons that move past the point. The value of 𝑁 depends on the density of free electrons in a substance, 𝑛, and the volume ...
