Positive static charge is only because it lost ____________ __________ not because it gained ____________ _____________.
What happens when if an object keeps gaining negative electrons? When the _____________ __________ is charge object and any “earthed” or grounded object is large enough, the electrons can __________ across the gap between two materials, causing a spark.
