Calculate the total resistance, amperage and voltage at the ends of each conductor if the voltage in the entire circuit is 10V, R1 = 4Ω, R2 = 6Ω, R3 = 2.6Ω.

Determine the total resistance in the section with parallel connection of R1 and R2.

R12 = R1 * R2 / (R1 + R2) = 4 * 6/10 = 2.4 ohms.

Determine the total resistance of the circuit.

Rob = R12 + R3 = 2.4 + 2.6 = 5 ohms.

Determine the current strength of the circuit. I = I3 = U / Rob = 10/5 = 2 A.

Determine the voltage across the resistance R3.

U3 = I3 * R3 = 2 * 2.6 = 5.2 B.

The voltage across the resistances R1 and R2 is the same and equal: U1 = U1 = U – U2 = 10 – 5.2 = 4.8 V.

The current through the resistor R1 is: I1 = U1 / R1 = 4.8 / 6 = 0.8 A.

The current passing through the resistor R2 is: I2 = U2 / R2 = 4.8 / 4 = 1.2 A.

Answer: Rob = 5 Ohm, I1 = 0.8 A, I2 = 1.2 A, I3 = 2 A, U1 = U2 = 4.8 B, U3 = 5.2 B.
