What is the ratio of intensity of electric field and current density? Answer : The ratio of the intensity of the electric field (\( E \)) to the current density (\( J \)) is given by the **electrical conductivity** (\( \sigma \)) of the material. This relationship can be expressed as: \[ ... of \( E \) to \( J \), and vice versa. Let me know if you'd like more details!...
