Questions 3-4:
A lamp, a voltmeter V, an ammeter A, and a battery with zero internal resistance are connected as shown.
3. How would the ammeter reading change when another lamp is connected in parallel with the first lamp as shown by the dashed lines?
(A) increases, because the current through the ammeter splits to feed both branches
(B) remains the same, because the ammeter measures the current provided by the battery
(C) decreases, because the resistance of the circuit is increased
(D) remains the same, because energy is conserved in the circuit
