Name: Electromotive Force: Terminal Voltage
ID: m42357
Language: English (en)
Summary:
  • Compare and contrast the voltage and the electromagnetic force of an electric power source.
  • Describe what happens to the terminal voltage, current, and power delivered to a load as internal resistance of the voltage source increases (due to aging of batteries, for example).
  • Explain why it is beneficial to use more than one voltage source connected in parallel.
Subject: Science and Technology
