What should be the voltage at the ends of the circuit section so that the current in the conductor is 1.0A, if at a voltage of 3V the current in the same conductor is 0.5A?
Initial data: I1 (required current in the circuit) = 1 A; U1 (initial voltage at the ends of the circuit section) = 3 V; I1 (initial amperage) = 0.5 A.
The desired voltage at the ends of the circuit section is determined from the equality: R = const = U1 / I1 = U2 / I2, whence U2 = U1 * I2 / I1.
Calculation: U2 = 3 * 1 / 0.5 = 6 V.
Answer: The voltage at the ends of the circuit section should be 6 V.
