Series and parrael circuits

• what happens in series circuit?


  Current flows through all components
• What happens in parrael circuit?


  Current splits up at same stage because you have 2 or more loops
• 1)current is same size at all points in circuit

  Series rule
• Adding bulbs make blub dimmer why?


  It reduces current flowing in series current
• Potential difference rule) 


  The p.d of battery is shared between bulbs
• If the bulbs are same...


  The share is equal
• Resistance rule) total resistance in circuit is the sum of the individual resistance
