When the Hall voltage is zero when the semiconductor is? Answer : The Hall voltage in a semiconductor is zero when the semiconductor is **not subjected to any magnetic field** or when **no current flows through the material**. Here's why: 1. **No ... voltage is zero when there is either no current flowing or no magnetic field applied to the semiconductor**....
