The electric current densities at P and Q are in the ratio 1 : 1
- Current Density is defined as the electric current flowing per unit cross-section area through a conductor.
- The electric current density is given by :
J = I / A
- Since the conductor is same and the current flowing through it is not changing,
Jp / Jq = (I / A) / (I / A) = 1 / 1
- Thus, Jp : Jq = 1 : 1
