DC Generator

• What is the function of a generator in a circuit?

  It converts mechanical energy to electrical energy
• How do splitting rings affect connections in a circuit?

  They change the coil connections every half turn
• What happens to connections when the induced potential difference changes direction?

  The connections are reversed in the circuit
• In what direction does the current flow in relation to the external circuit?

  It always flows in the same direction
• What can increase the maximum potential difference or current?

  Increasing the rate of rotation
• What is another way to increase the maximum potential difference?

  Increasing the strength of the magnetic field
• How can the number of turns on the coil affect the current?

  Increasing turns can increase the current
• What factors can increase the current in a generator?

  • Increasing the rate of rotation
  • Increasing the strength of the magnetic field
  • Increasing the number of turns on the coil
• What is a transformer in the context of electrical circuits?

  A device that changes voltage levels
• What is the role of a transformer in power distribution?

  It steps up or steps down voltage
• How does increasing the number of turns in a transformer affect voltage?

  More turns increase the output voltage
• What is the relationship between voltage and current in a transformer?

  Voltage increases as current decreases
• Why is it important to step up voltage for long-distance transmission?

  It reduces energy loss during transmission
• What are the key components of a generator system?

  • Generator (converts mechanical to electrical energy)
  • Splitting rings (change coil connections)
  • Magnetic field (affects potential difference)
  • Coil (number of turns affects current)
