1)Several resistors are connected in series. If a battery provides constant voltage in this circuit the addition of another resistor in series
a)increases current through each resistor
b)decreases current through each resistor
c)doesn't affect the current throught any resistor
d)doesn't affect the current throught some resistors

Isn't the correct answer B since it's in series?

2)Several resistors are connected in series. If a battery provides constant voltage in this circuit the addition of another resistor in series
a)increases voltage through each resistor
b)decreases voltage through each resistor
c)doesn't affect the voltage across any resistor
d)doesn't affect the voltage across some resistors

Isn't it A? V=IR and as R increases V also increases.
