Question

N resistors (N > 2) are connected in parallel with a battery of voltage Vo. If one of the resistors is
removed from the circuit, which of the following quantities will decrease?
I. The voltage across any of the remaining resistors
II. The current output by the battery
III. The total power dissipated in the circuit

Answer 1

Your voltage is constant; since the resistors are in parallel that rules out I
Your total resistance increases; since V=IR, I=V/R your current decreases II is true
P = VI since your current decreases so does your power.
