Suppose that after walking across a carpeted floor you reach for a doorknob and just before you touch it a spark jumps 0.95cm from your finger to the knob. Find the minimum voltage needed between your finger and the doorknob to generate this spark. The minimum field that can produce a spark in air is 3.0x10^6 V/m. V = V
