The Pole Core is use to reduce

Is an electromechanical instrument used for detecting and indicating an electric current.

It is a fault that occur from the negative to positive brushes which is equivalent to a short circuit

It later replaced cast iron for yokes.

The change of Generator voltage from no-load to full-load

A device use to measure the RPM of a Dynamo

Is generally restricted to low-voltage high-current machines.

Is an apparatus mounted on the roof of an electric train, tram, or electric bus to collect power through contact with an overhead line.

It serves as a rectifier in a DC dynamo

A low resistance connected in shunt directly across the series field. It diverts or bypasses part of the loads current Through a section of wire That creates no flux. I hi no-load voltage may be brought up to almost any desired value to meet the individual demands.

Generally rotating electrical machine that converts electrical

energy into mechanical energy or vice-versa.

Reverses connection to the external circuit at the same instant that the direction of EMF reverses in each of the coil side^. Each brush, therefore positive or negative respectively, is always maintained at the same polarity.

Have combine characteristics of Shunt and Series generators.

The Figure shown is an example of a

Reduce voltage is one of the effects of

The right hand rule of Fleming is use for

Are coils that are placed between the field coils that generate a field that is used to prevent excessive sparking on the brushes.

The rising projection whose function is to connect to the ends of the armature coils.

The two general types of dynamo are

Is the conversion of Electrical Power to Mechanical Power or vice versa

It has both the series field and the shunt field windings which are connected either long shunt or short shunt.

The speed at which a dynamo is acting as a generator operates, is determined by the speed load characteristics which is of a _________________.

What will happen if a synchronous Motor is use to drive the Generator?

Dynamos having shunt series or compound fields will serve as motors as well generators, but each will have respect to ____________________________

This is a _________________. And to reverse the rotation of this kind of motor, you need to interchange the position of the ___________.

The kind of motor in the Figure of number 27 is

Choose the correct item below corresponding to the letters in the Figure.

What do you call this part of the armature? Please see the bracket with a question mark on the Figure.

Refers to the number of close loops formed by the completed armature winding.

An armature winding always forms at least one closed loop describe as ________________

The Figure is a

Front-Pitch is the number of slot spans included between the ______________, which connects to the same commutator bars

All inductors taken as a group, which lie on a single slot

Consist of heavy copper conductors which connects points on the armature winding two poles apart & which normally should be at the same potential. These connections may be to copper rings on the pulley end of the armature.

The Figure shows the External Characteristic of a ____________________ generator at No-Load
