A conductor which is 36 m long has a resistance of 7.41mΩ per meter calculate its end to end resistance
A) 0.26mΩ
B) 2.66Ω
C) 0.26Ω
D) 2.66mΩ

Question

Quizplus · Accepted Answer

The end-to-end resistance of the conductor can be calculated as:
Total resistance = Resistance per meter x Length
Total resistance = 7.41 mΩ/m x 36 m 
Total resistance = 266.76 mΩ 
Converting to Ω: 
Total resistance = 0.26676 Ω 
Therefore, the correct choice is C) 0.26Ω, which is the nearest option in terms of significant figures.
