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

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 with a current of 0.2 A?

To calculate the voltage in the used conductor, we use the equality: U0 / I0 = R (conductor resistance) = U1 / I1, whence U1 = U0 * I1 / I0.

Variable values: U0 – initial voltage (U0 = 2 V); I0 – initial current strength (I0 = 0.8 A); I1 is the current strength under consideration (I1 = 0.2 A).

Let’s do the calculation: I1 = U1 = U0 * I1 / I0 = 2 * 0.2 / 0.8 = 0.5 V.

Answer: The voltage will be 0.5 V.
