The section of the electrical circuit contains three conductors with a resistance of 10 ohms, 20 ohms and 30 ohms

The section of the electrical circuit contains three conductors with a resistance of 10 ohms, 20 ohms and 30 ohms, connected in series. Calculate the current in the first conductor, the voltages at the ends of the first and third conductors, and the voltage at the ends of the entire section if the voltage at the ends of the second section is 40 V.

1) the amperage in series connection is the same
2) I2 = U2 / r2 = 2A
3) U1 = I * R1 = 2 * 10 = 20 B
U3 = I * R3 = 2 * 30 = 60 V
Answer: I = 2A, U1 = 20B, U3 = 60B
