Electrical

Question 1

What is the equation for current including drift velocity?

Answer 1

I=VdrhoA

I is current, Vd is drift velocity, rho is charge density (property of a material) and A is cross sectional area.

Question 2

How do you find the electrical field difference between 2 ends of a wire?

Answer 2

E=V/L

E is the difference in electric field, V is voltage and L the length of wire?
