Electrical Resistance

Electrical Resistance

 

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,

• To define electrical resistance in terms of energy transfer,

• Realizing that the bulb also has a resistance.
