What would happen when two or more capacitors are connected in series across a potential difference, then

1) the net potential difference of the circuit will be the sum of all the potential difference of all the individual capacitors that are connected together.

2) The net capacitance in the circuit would be lesser than that of the capacitance of the individual capacitors.

3) the charges on the individual capacitors will remain the same.

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
