Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is 10.0 Ω.Key Points
- The formula for calculating resistance is R = V/I, where V is the potential difference and I is the current flowing through the wire.
- Plugging in the given values, R = 5.0 V / 0.5 A = 10.0 Ω.
- Therefore, the correct answer is 10.0 Ω.
- Copper wire is a good conductor of electricity due to its high electrical conductivity and low resistivity.
Additional Information
- The difference in charge carrier energy between two places in a circuit is known as the potential difference.
- The ease with which an electric current can pass through a material is measured by its electrical conductivity.
- The amount of obstruction to current passage in an electrical circuit is measured as resistance.
