SUMMARY

The discussion centers on the control of current transmission in power transformers, specifically whether it is governed by the generator's output or the resistance of the transmission cable. It is established that a generator provides a constant voltage, while the load determines the current drawn based on its resistance. If the load demands more current than the generator can supply, the generator risks damage or operational failure.

PREREQUISITES
  • Understanding of electrical concepts such as voltage, current, and resistance
  • Familiarity with power generation principles and generator operation
  • Knowledge of transmission line theory and its impact on current flow
  • Basic grasp of load characteristics in electrical systems
NEXT STEPS
  • Research the principles of Ohm's Law and its application in electrical circuits
  • Explore the operational limits and safety mechanisms of electrical generators
  • Learn about transmission line resistance and its effects on power delivery
  • Investigate load management techniques in power systems
USEFUL FOR

Electrical engineers, power system analysts, and anyone involved in the design or operation of electrical generation and transmission systems.

Current transmitted control by the input power from the generator or control by the resistance of the transmission cabel?

Welcome to PF.

I'm guessing we you used google translator for this, which is why the post is difficult to read...

The current transmitted to a load is determined by the resistance of the load. A generator puts out a constant voltage and the load draws as much current as it wants. The generator provides this current or fails trying (either destroyed in the effort or the mover of the generator can't keep up).
