5. What is electric resistance) How is it used in an electric bulb? long answer.
Answers
Answer:
Electricity flows through a thin tungsten wire in the light bulb called the filament. The filament used in a bulb has a property called "resistance." Resistance is the amount of friction that an object will put against electricity flowing through it. A filament has a lot of resistance to electricity
The electrical resistance of a circuit is the ratio between the voltage applied to the current flowing through it. The unit of electrical resistance is ohms. Electric charge flows easily through some materials than others.Electricity flows through a thin tungsten wire in the light bulb called the filament.
