I answered that: I think Weichen is right b/c according to the equation Iseries = I1 = I2, the bulbs in a series circuit would be all using the same amount of current as the battery. It is also easier to control current in a parallel circuit, i.e, one can cut off power to a set or individual bulbs without breaking the circuit completely.

6. Ray and Weichen are having an argument! Weichen thinks a battery will be worn out faster when it is connected to bulbs in series and Ray thinks a battery will be worn out faster when it is connected to bulbs in parallel. Who is correct?
