The total voltage of circuit K & L are...

• Circuit K = 18 volts

  Circuit L = 8 volts

• Circuit K = 9 volts

  Circuit L = 9 volts

• Circuit K = 18 volts

  Circuit L = 9 volts

Choose the correct option that describes the relationship between current & voltage.

• Circuit K has a higher total voltage and therefore more current flowing through it than circuit L

• Circuit K has a higher total voltage and therefore less current flowing through it than circuit L
