first as in circuit (1)
Three identical cells, each having an e.m.f. of 1.5 V and a constant internal resistance of 2.0Ω, are connected in series with a 4.0 Ω resistance R, first as in circuit (1), and second as in circuit (ii). what is the ratio Power in R in circuit (ii)/Power in R in circuit (i) ?
