Determine the current in the conductor if the voltage at its ends is 100 V, the length of the conductor is 2 m, the cross-sectional area of the conductor is 0.0004 m squared, the resistivity of the conductor is 0.08 Ohm multiplied by m.
we find the resistance of the conductor by the formula R = Pl / S, where P is the specific resistance of the conductor, l is the length of the conductor, S is the area of the transverse
conductor cross-section
R = 0.08 * 2 / 0.0004 = 400 Ohm
I = U / R = 100V / 400 Ohm = 0.25A
Answer: 0.25A
