Multiple Choice

Which option correctly explains how to construct the circuit so the bulb lights?

• Move Wire X so it goes from the negative side of the battery to

  the positive side of the battery.

• Move Wire Y so it connects the positive side of the battery to the

  left contact of the bulb holder.

• Move Wire Y so it connects the negative side of the battery to the

  right contact of the battery holder.

• Move Wire X so it goes from the left contact of the bulb holder to

  the negative side of the battery.

Multiple Choice
