A 0.9 V potential difference is maintained across a 1.5 m length of tungsten wire that has a cross-sectional area of 0.6 mm^2. Given the resistivity of tungsten is 5.6 x 10^-8 Ī©Ā·m, what is the current in the wire?

Step 1
9 V - Length of the wire (L) = 1.5 m - Cross-sectional area (A) = 0.6 mmĀ² = 0.6 x 10^-6 mĀ² - Resistivity of tungsten (Ļ) = 5.6 x 10^-8 Ī©Ā·m Show moreā¦
