Objectives
• Observing the relationship between the number of bulbs and the brightness of the bulb,
• To examine the effects of the length of the conductor in the circuit, the vertical cross-sectional area and the type of the conductor on the brightness of the bulb,
• To estimate the variables on which the brightness of a light bulb connected to an electrical circuit depends,
• Realizing that the bulb also has a resistance.
