A closed circuit is a kind of electric circuit in which the path that the electrons follow forms a complete circuit.
it is one of method to turn off scr. resonating LC component is used to turn off scr
They can be used as a kind of safety switch to allow a circuit with a small current through to switch on a circuit that will hve a larger current flowing through it.
it can be either, depending on parts used in the circuit and their connections.
A commutation switch is a device used to reverse the direction of current flow in a circuit, typically in motor control applications to control the direction of rotation. It allows for the smooth transition of current between different circuit elements, such as switching from one winding to another in a motor to maintain torque.
chopper transforms ac to dc (dc chopper) while all inverter transform dc to ac commutation used in chopper: forced,load commutation used in inverter:forced(180 vsi),natural or line(120 vsi)
The term "Forced commutation" is used when a thyristor is turned off using external components. If a thyristor is used in a DC circuit, when first turned on, it will stay on until the current goes to zero. To turn off the thyristor it is possible to use a Forced commutation circuit. The circuit creates a reverse voltage over the thyristor (and a small reverse current) for a short time, but long enough to turn off the thyristor. A simple circuit consist of a precharged capacitor and a switch (e.g. another thyristor) parallel to the thyristor. When the switch is closed, the current is supplied by the capacitor for a short while. This cause a reversed voltage over the thyristor, and the thyristor is turned off.

Simply, direct current (DC). The amount of current depends on the circuit it is used in.
The French Horn was invented in 1753, it was invented because it was used for commutation and for the beautiful sound it made.
