By shuffling her stocking feet across a carpet a person accumulates 1µC  of electrons which put her at 200 V above her surroundings.    Since air will break down (and conduct electricity) at a field strength of 3 x 104  N/C, when she puts her hand out to touch the doorknob, she will create a spark, losing all her charge with average current which is an amazing, but very brief, 0.8 amp.  

What is her effective capacitance?
