it can represent only the finite state machine.In such a machine an arbitrarily long sequence of input symbols is bound to create a periodic output with a period not more than the number of states.hence computations that need to remember an arbitrary number of past input symbols cant be implemented by seq machines
State diagrams are used to model the behavior of sequential circuits by showing the different states the circuit can be in and the transitions between those states based on inputs. Each state represents a unique condition or behavior of the circuit, and the transitions show how the circuit moves from one state to another in response to input changes. By visually depicting the states and transitions, state diagrams help in designing and analyzing sequential circuits for correct operation.
Flip-flops are commonly used in VLSI physical design for sequential logic circuits due to their ability to store binary information and synchronize signals. They help in controlling the timing of signals and reduce the chances of metastability issues. Flip-flops also provide a way to control the state of a circuit at specific clock edges, aiding in sequential circuit design.
that is called a perfect circuit
In electrical engineering, parallel circuits have multiple paths for current flow, while series circuits have only one path. Parallel circuits have the same voltage across each component, while series circuits have the same current flowing through each component.
Energy sources are not always present in circuits as some circuits rely on energy harvested from the environment.
A circuit is a plan of exercises one does to get fit and a sequential circuit is a set of these one does one after the other, it is called circuit training.
Advantages of sequential circuits
Sequential Logic circuits are a type of logic circuits in which its output depends on the current and last input (memory). a digital circuits that contain filp-flop is called as sequential ckt because its output at any time depend not only on its current input but also past sequence memory of past event.

combinational circuit
Washing machines, dryers, dishwashers.
A sequential circuit is a type of logic circuit. It sends an output that is dependent upon the present input in addition to the history of the input. That makes it different from a combinational circuit, whose output depends solely on the present input. Given their reliance on input history (or stored input), sequential circuits are particularly useful in computer random access memory (RAM). The two types of sequential circuits are synchronous circuits and asynchronous circuits.

both combinational and sequential circuits have two inputs and outputs..!
