Answer:
electric charges are quantised
Step-by-step explanation:
which means they exist as integral multiples q=ne . this was practically proved by the Millikan's oil drop experiment in which he let charged oil droplets as fine as mist fall under the effect of gravity, after measuring the charge on many drops the results showed that charges were multiples of a minimum value 1.6 x 10
which we now know as the charge on an electron or elementary charge.
