Yes.yes they do
When the centers of both the circles are at the same point.
There is such a point only if all the circles are concentric.
Ripple voltage is a voltage with an impure wave that isn't stable at all. Usually when you overload an AC to DC converter, it tends to do that.
A ripple counter is a counter in which state transitions of one or more flip flops are triggered by the outputs of other flip flops in the circuit. If all flip flops in the counter are triggered by a common clock pulse, then the counter is called a "synchronous counter". a ripple counter is a counter that will ripple through the information sequentialy. .
The center of a ripple is called the focal point. This is where the disturbance that creates the ripple originates, spreading outwards in concentric circles.

Concentric circles are circles with the same common centre.

Close - they're called concentric circles.
Since pies are circular, the pie shaped pieces will be more concentric circles.
If you mean they both have the same centre - they're called 'concentric' circles.
Yes. The circles can be of different size. These are called concentric circles.
