parrallel circuits- current has a choice

• What flows out of the cell in a circuit?

  Current
• Through which ammeter does all the current flow initially?

  The first ammeter (A1)
• How many routes can the current split into?

  Three routes
• What determines the readings of the other ammeters?

  The resistance of components
• What happens to the currents on the way back to the cell?

  They join up again
• What is the relationship between the readings of all the ammeters and the first ammeter?

  They add up to the first one
• In a parallel circuit, what can happen to parts of the circuit?

  Some parts can be on while others are off
