What is the purpose of commutator?
To reverse the direction of the current, and keep the thing ( rotor, armature) going in one direction. The older term, applied to some automobile use, was timer. The French correctly refer to the Balance Wheel of a watch as a commutator, using the French spelling of commutateur. Some expensive watches had solid Gold commuator screws on the balance wheel!
What is generally not a possible condition in an electric circuit?
Current cannot flow through an open circuit.
What is a condition that provides an undesired path for electrical current?
The condition you are looking for is a short circuit.
What is the Relationship between resistance and inductance in a RL circuit?
What is the Relationship between resistance and inductance in a RL circuit?
What is inductor functioning?
Actually Inductor oppose the change of current in the circuit..... Acts like a short circuit in steady state condition....
How commutator converts AC to DC?
There is no conversion of AC to DC a commutator is the key to creating straight DC voltage. "The commutator rotates with the loop of wire just as the slip rings do with the rotor of an AC generator. Each half of the commutator ring is called a commutator segment and is insulated from the other half. Each end of the rotating loop of wire is connected to a commutator segment. Two carbon brushes connected to the outside circuit rest against the rotating commutator. One brush conducts the current out of the generator, and the other brush feeds it in. The commutator is designed so that, no matter how the current in the loop alternates, the commutator segment containing the outward-going current is always against the "out" brush at the proper time. The armature in a large DC generator has many coils of wire and commutator segments. Because of the commutator, engineers have found it necessary to have the armature serve as the rotor(the rotating part of an apparatus) and the field structure as the stator (a stationary portion enclosing rotating parts). Which is the inverse of an AC Generator."
What is the difference between a series circuit and a parallel cicuit and condition?
is it g style
What component of a motor changes the induced AC voltage into a pulsating DC?
The commutator is the moving part of the electrical switch in motors that reverses the current direction between the rotor and the external circuit. This is applicable in electrical motors and electrical generators.
Why you use carbon for making connection to DC motor?
Carbon brushes are used to connect the rotating commutator of a DC machine with the external circuit. Carbon is selected becauseit has a negative temperature coefficient of resistance, i.e. its resistance falls with a rise in temperature.it is self-lubricating.it quickly shapes itself to the curve of the commutator.
What is the different between a fuse and a switch?
A switch is an isolation device in a power circuit. A fuse is self destructing safety device in a circuit. Fuse burns out under an overload (current) condition and cuts off and isolates the circuit.
Does a polygon have sides that are line segments?
A polygon is defined as "a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit"... So - Yes.
Condition of resonance in RLC circuit?
XL=Xc is the resonance condition for an RLC circuit
What is a condition that provides an undesired path for electrical current?
The condition you are looking for is a short circuit.
What is generally not a possible condition in an electric circuit?
Current cannot flow through an open circuit.
What type of circuit fault is a blown fuse?
Circuit Condition Created by a "Blown" FuseA blown fuse creates an "open" circuit condition. It's the same as opening a switch [turning a switch to the off position].

What is the difference between ac and dc generators?
AC generator, the brushes run on slip rings which maintain a constant connection between the rotating coil and the external circuit. This means that as the induced emf changes polarity with every half-turn of the coil, the voltage in the external circuit varies like a sine wave and the current alternates direction. DC generator, the brushes run on a split-ring commutator which reverses the connection between the coil and the external circuit for every half-turn of the coil. This means that as the induced emf changes polarity with every half-turn of the coil, the voltage in the external circuit fluctuates between zero and a maximum while the current flows in one constant direction
