MRSO PREP EXAM WITH ALL CORRECT ANSWERS.docx Zero Boil-Off - Answer-System that reduces/eliminates the need to recharge Helium in a magnet. Quench - Answer-Quickly eliminating the magnetic field. Not immediate, takes 3 to 5 minutes to completely eliminate magnetic field. Loud Noise as Helium rushes out of Quench Vent. Can cause crack in the wire (very costly to repair/replace). Ohm's Law - Answer-Resistance that is equal to Voltage divided by the amperage in a wire. V=IR U...
