Question

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

Isn't the correct answer a)?

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

shouldn't c) be the answer because voltage is the same throughout resistors that are placed in parallel?

Answer 1

c, and c.
