The ideal battery in Fig. 27-39 a has emf ℰ = 6.0 V. Plot 1 in Fig. 27-39 b gives the electric potential difference V that can appear across resistor 1 versus the current i in that resistor when the resistor is individually tested by putting a variable potential across it. The scale of the V axis is set by V s = 18.0 V. and the scale of the i axis is set by i s = 3.00 mA. Plots 2 and 3 are similar plots for resistors 2 and 3, respectively, when they are individually tested by putting a variable potential across them. What is the current in resistor 2 in the circuit of Fig. 27-39 a ? Figure 27-39 Problem 28.

In Fig. 27-26, the ideal batterieshave emfs E1=150 V and E2=50 Vand the resistances are R1 = 3.0 0 andR2 = 2.0 0. If the potential at P is 100 V,what is it at Q?
A resistor with R1 = 25.0 Ω is connected to a battery that has negligible internal resistance and electrical energy is dissipated by R1 at a rate of 36.0 W. If a second resistor with R2 = 15.0 Ω is connected in series with R1, what is the total rate at which electrical energy is dissipated by the two resistors?
A cylindrical metal wire at room temperature is carrying electric current between its ends. One end is at potential VA = 50 V, and the other end at potential VB = 0 V. Rank the following actions in terms of the change that each one separately would produce in the current, from the greatest increase to the greatest decrease. In your ranking, note any cases of equality. (a) Make VA = 150 V with VB = 0 V. (b) Make VA = 150 V with VB = 100 V. (c) Adjust VA to triple the power with which the wire converts electrically transmitted energy into internal energy. (d) Double the radius of the wire. (e) Double the length of the wire. (f) Double the Celsius temperature of the wire. (g) Change the material to an insulator
