We can construct a simple circuit with a battery and a bulb to produce electricity. The requirements of this experiment is a battery, a bulb and two copper wires. 
Procedure:
  • Remove the insulating material from the two ends of the copper wires. Connect one end of the wire to the negative end of the battery. Make sure that the wire touching the lower part of the battery.
  • Connect the other end of the battery to the bulb using other wire. We can light the bulb by touching the two ends of the battery accordingly.
  • We can use some optional materials to make this process easier. Use switches to on and off the bulb.
The cell provides a direct current to the bulb. This current has a unique direction and it flows from the positive terminal of cell to its negative terminal through the bulb. The magnitude of the current given by the cell remains constant for a sufficiently long time. When the cell gets discharged, it stops giving current and becomes useless.
