• A)The charges are moving slower at point b than at point a.
• B)The electric potential is lower at point b than at point a.
• C)The electric potential is higher at point b than at point a.
• D)The current at point b is the same as the current at point a.
• E)The electric potential at point b is the same as it is at point a.

Definitions:

Cumulative-compound

Refers to a type of DC generator where both series and shunt field windings add their magnetic fluxes to produce the total output voltage.

Shunt Field

A coil wound with small wire and having many turns designed to be connected in parallel with the armature of a DC machine.

Series Field

A winding of large wire and few turns designed to be connected in series with the armature of a DC machine.

Frogleg-wound

A type of armature winding in electric motors and generators that resembles the legs of a frog spread out, used to achieve certain magnetic and electrical properties.
