Solution: a b c d 5 Ω 3 Ω 5 Ω 5 Ω 3 Ω 6 Ω 6 Ω c d 5 Ω 5 Ω 12 Ω 6 Ω R eq c d 5 Ω 5 Ω 4 Ω R eq R eq = 4 + 5 + 5 = 14 Ω . Problem 2.35 Simplify the circuit to the right of terminals ( a , b ) in Fig. P2.35 to find R eq , and then determine the amount of power supplied by the voltage source. All resistances are in ohms. Solution: 25 V 3 5 8 6 6 8 4 12 12 a b + _ R eq 25 V 3 5 8 6 8 4 12 4 a b + _ R eq 25 V 3 5 6 8 4 6 12 || 12 = 6 8 || 8 || 4 = 2 5 + 6 || 6 = 5 + 3 = 8 a b + _ R eq 25 V 3 8 4 8 a b + _ R eq 25 V 3 2 a b + _ R eq Figure P2.35: Circuit for Problem 2.35. R eq = 3 + 2 = 5 Ω P = V 2 R eq = ( 25 ) 2 5 = 125 W . Problem 2.36 For the circuit in Fig. P2.36, determine R eq at (a) Terminals ( a , b ) (b) Terminals ( a , c ) (c) Terminals ( a , d ) (d) Terminals ( a , f ) e f b a c d 2 Ω 2 Ω 2 Ω 2 Ω 2 Ω 2 Ω 2 Ω 2 Ω 2 Ω 2 Ω Figure P2.36: Circuit for Problem 2.36....
