What is a Commutator? Commutators are used in DC machines (DC motors and DC generators) universal motors In a motor, a commutator applies an electric current to the windings A steady rotating torque is produced by reversing the current direction in the rotating windings each half turn In a generator, the commutator reverses the current direction with each turn serving as a mechanical

The second way is to look at the commutator subgroup as a measure of how noncommutative a group is A group is commutative if it has a trivial commutator subgroup (and highly noncommutative if the commutator subgroup is the entire group)
- The commutator of two matrices - Mathematics Stack Exchange
The commutator [X, Y] of two matrices is defined by the equation $$\begin {align} [X, Y] = XY − YX \end {align}$$ Two anti-commuting matrices A and B satisfy $$\begin {align} A^2=I \qu
- How to show that the commutator subgroup is a normal subgroup
The commutator subgroup is generated by commutators Show that the property of "being a commutator" is invariant under conjuation (in fact it is invariant under all automorphisms)
- Why is the commutator defined differently for groups and rings?
The commutator of a group and a commutator of a ring, though similar, are fundamentally different, as you say In each case, however, the commutator measures the "extent" to which two elements fail to commute
- Commutator relationship proof $ [A,B^2] = 2B [A,B]$
These are supposed to be quantum mechanics operators Well, I was hoping to show algebraically that [A,B] must necessarily be something like a constant
- What is commutator? Physics Q A - BYJUS
A commutator is a piece of equipment linked to the armature of such a motor as well as a dynamo that makes an electrical linkage as well as guarantees the amount of current flowing via direct current Function of commutator It is being utilized to reverse the current at such a position as well as time to prevent the torque on such a DC motor from switching every other moment the coil goes
- Commutator of $p^2$ and $x$ - Mathematics Stack Exchange
Writing in more details, the commutator relation is $$ [p,x]=-i\hbar I$$ where $I$ is the identity operator So $pi\hbar$ should be understood as $pi\hbar I$, the composition of the two operators $p$ and $i\hbar I$
