To solve the question regarding the scalar product of current density \(\vec{j}\) and electric field \(\vec{E}\) inside a current-carrying conductor, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Current Density and Electric Field**: - Current density \(\vec{j}\) is defined as the current per unit area flowing through a conductor. It has a direction that is the same as that of the current. - The electric field \(\vec{E}\) inside the conductor is related to the potential difference and also points in the direction of the current flow. ...
