Students in an introductory physics lab are producing a region of uniform electric field by applying a voltage to two 20-cmdiameter aluminum plates separated by 2.5 cm. They connect the two plates to the two terminals of a high-voltage power supply and then gradually turn up the voltage. In such a situation, sparks start to fly when the field exceeds 3 x 106 V/m. What is the highest voltage the students can use?
