What is the turns ratio in a transformer?
Answer : The **turns ratio** in a transformer is the ratio of the number of turns of wire in the primary coil (input side) to the number of turns in the secondary coil (output side). ... to the secondary coil determines whether the transformer increases or decreases the voltage (and inversely, the current)....

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!...
