Voltage distance at elevation

Ask an Expert Topic Forum: Grades K-5: Physical Science

Voltage distance at elevation Voltage distance at elevation My son is conducting the static charge experiment and is trying to determine voltage. The formula says that it takes 30,000 V to travel 1 cm at 1 atm. Using an air pressure calculator, we have determined that our atm at 7400ft is .76 atm. Would it take 30,000v / .76 = ~40,000V to travel 1cm at elevation of 7400ft? Or should our calculation be 30,000V * .76 = ~22,500v to travel 1cm at elevation of 7400 ft?
