Question 25: For the circuit shown in Figure 7.76, find: (a) the current and the potential difference for each resistor; (b) the potential difference VA - VB (the directions given to the currents in the figure are arbitrary). (c) Check that the net power supplied by the batteries is fully transformed into heat in the resistors. Answer: (a) I2= 3.00 A ; I2= 1.00 A, in the opposite direction of the figure ; I3= 4,00 A in the opposite direction of the figure; ∆VR1= 6.00 V ; ∆VR2= 5.00 V ; ∆VR3= 20.0 V ; (b) -20.0 V (c) 103W
