Question 1 Report

A student measures the potential difference V and current I for five different resistors. The table shows the results.

Which resistor has a resistance of 24 Ω?

Answer Details

Using \(R = \frac{V}{I}\), calculate the resistance of each resistor:

A: \(R = \frac{4.5}{0.30} = 15\;\Omega\)
B: \(R = \frac{7.2}{0.60} = 12\;\Omega\)
C: \(R = \frac{3.6}{0.15} = 24\;\Omega\)
D: \(R = \frac{9.0}{0.45} = 20\;\Omega\)
E: \(R = \frac{5.4}{0.36} = 15\;\Omega\)

Resistor C has a resistance of 24 Ω.
