When the voltage at the ends of the conductor is 2 V, the current is 0.8 A.

When the voltage at the ends of the conductor is 2 V, the current is 0.8 A. What is the voltage on this conductor when the current is 1.6 A?

Initial data: U1 (initial voltage at the ends of the conductor) = 2 V; I (initial current in the conductor) = 0.8 A; I (final value of the current in the conductor) = 1.6 A.

We find the voltage on the conductor at a current of 1.6 A from the equality: U1 / I1 = R = U2 / I2, whence U2 = U1 * I2 / I1.

Let’s do the calculation:

U2 = 2 * 1.6 / 0.8 = 4 V.

Answer: With a current in the conductor of 1.6 A, the voltage will be 4 V.
