A-LevelPhysicsD.C. circuitsOct/Nov 2017Paper 2 Q53 Marks
Three cells of electromotive forces (e.m.f.) E₁, E₂ and E₃ are connected into a circuit, as shown in Fig. 5.1. The circuit contains resistors of resistances R₁, R₂, R₃ and R₄. The currents in the different parts of the circuit are I₁, I₂ and I₃. The cells have negligible internal resistance. Use Kirchhoff's laws to state an equation relating [Figure 5.1]
