1. Referring to Fig. 4-1, reverse the polarity of battery En and the current direction through resistor Rg. (a) Write Kirchhoff's current equation at junction p. (6) Write Kirehhoff's voltage equation for cirouit bqnmfpb. * Referring to Fig. 4-2, change Ra to 0.2 ohm, Rp to 0.3 ohm, and Rz to 0.5 ohm. With the same battery polarities, and with EA as shown, calculate (a) the carrents Ir L. and In: (6) the load voltage VLi (c) the load and battery powers PL, PA, and Pa. 24 volts and En 26 volte 3. Referring to Fig. 4-2, what will be the current in the load resistor RL if (a) battery B is replaced by a wire of negligible resistance? (b) battery A is replaced by a wire of negligible resistance? 4. What will be the current in the circuit of Fig. 4-2 if the load resistor RL is removed? assumed RF Ro www IF RE www IE (+) EB Rc RB 9.
