A current of 0.40 A flows through the conductor, the potential difference at the ends of the conductor is 8.0 V. What is the resistance?
Initial data: I (current in the conductor) = 0.4 A; φ1 – φ2 (potential difference) = U (voltage, true only for a homogeneous section of the circuit) = 8 V.
Conductor resistance can be determined by the formula: R = (φ1 – φ2) / I = U / I.
Let’s calculate: R = 8 / 0.4 = 20 Ohm.
Answer: The resistance of the conductor is 20 ohms.
