Filament Lamp

• What is the effect of temperature on filament lamps?

  Resistance increases as temperature rises
• Why does resistance increase in filament lamps with temperature?

  Higher temperature causes more metal ions to vibrate
• How does increased temperature affect electron movement in filament lamps?

  It makes it harder for electrons to move
• What is the relationship between temperature and the metal ions in filament lamps?

  Metal ions vibrate more at higher temperatures
• What happens to the filament lamp's resistance as the temperature increases?

  Resistance increases due to more vibrations
• What is the impact of increased resistance on electron movement in filament lamps?

  It hinders the movement of electrons
• What is the term for the difference in electrical potential in a circuit?

  Current potential difference
• Why is current potential difference important in circuits?

  It drives the flow of electric current
• How does current potential difference relate to resistance in a circuit?

  Higher resistance reduces current for a given potential
