A higher armature resistance in a DC motor leads to increased efficiency. True or False?

Understand the Problem

The question is asking whether having a higher armature resistance in a DC motor leads to increased efficiency. This involves understanding the relationship between armature resistance and motor efficiency.

More Information

A higher armature resistance in a DC motor leads to increased power losses, thereby reducing efficiency. Efficiency in DC motors can be influenced by the resistance of the armature, and higher resistance typically leads to reduced performance.

Tips

A common mistake is assuming that higher resistance might control power flow better; however, it increases losses and decreases efficiency.
