Question

∈₁ and ∈₂ are two batteries having emf of 34 V and 10 V respectively and internal resistance of 1 Ω and 2 Ω respectively. They are connected as shown in Figure 3 below. Using Kirchhoff’s’ Laws of electrical networks, calculate the currents I₁ and I₂.

Answer 1

In loop AFEBA

17 I₁ + 5I₂ = 34

In loop BEDCB

18 I₁ + 5I₂ = 10

Solving the Above two equations

I₁ = 2A, I₂ = 0
