Problem
For the circuit shown, the ammeter reading is initially I. The switch in the circuit then is closed. Consequently:
[Figure: Circuit diagram with ammeter, bulbs, switch, and points E and F marked]
(a) The ammeter reading decreases.
(b) The potential difference between E and F increases.
(c) The potential difference between E and F stays the same.
(d) Bulb #3 lights up more brightly.
(e) The power supplied by the battery decreases.
