Question

Find the current flowing through the resistance R₁ of the circuit shown in Fig. 3.48 if the resistances are equal to R₁ = 10 Ω, R₂ = 20 Ω, and R₃ = 30 Ω, and the potentials of points 1, 2, and 3 are equal to φ₁ = 10 V, φ₂ = 6 V, and φ₃ = 5 V.

Answer 1

Let us distribute the currents in the paths as shown in the figure.

Simplifying Eqs. (1) and (2) we get
