The voltage at the poles of the current source is 20 V. Find the voltage and current in each of the two series-connected conductors if R1 = 12 Ohm R2 = 5 Ohm.
Total circuit resistance for series connection:
R = R1 + R2, where R1 = 12 ohms, R2 = 5 ohms.
R = R1 + R2 = 12 + 5 = 17 ohms.
Amperage in each of the conductors when connected in series:
I1,2 = I1 = I2 = U / R, where U = 20 V.
I1,2 = U / R = 20/17 = 1.176 A.
Voltage on each conductor:
U1 = I1 * R1 = 1.176 * 12 = 14.1 V.
U2 = I2 * R2 = 1.176 * 5 = 5.9 V.
Answer: The current on each conductor is 1.176 A, the voltage on the first conductor is 14.1 V, on the second conductor 5.9 V.
