When resistors 1 and 2 are connected in series, the equivalent resistance is 20.7 (2. When they are connected in parallel, the equivalent resistance is 4.00 (2. What are (a) the smaller resistance and (b) the larger resistance of these two resistors? (a) Number n Units v (b) Number I Units v In the figure R1 = 7.14 02, R2 = 21.4 0, and the ideal battery has emf & = 11.6 V. (a) What is the magnitude of current i1? (b) How much energy is dissipated by all four resistors in 0.583 min? M 8 R1 M R2 (a) Number i Units (b) Number i UnitsIn the gure the current in resistance 6 is i6 = 1.39 A and the resistances are R1 = R2 = R3 = 1.87 0, R4 = 15.9 0, R5 = 8.08 (2, and R6 = 4.09 (2. What is the emf of the ideal battery? Number Units v You are given a number of 15 Q resistors, each capable of dissipating only 2.7 Wwithout being destroyed. What is the minimum number of such resistors that you need to combine in series or in parallel to make a 15 Q resistance that is capable of dissipating at least 10.4 W? Number I Units v A certain brand of hotdog cooker works by applying a potential difference of 139 V across opposite ends of a hot dog and allowing it to cook by means of the thermal energy produced. The current is 11.0 A, and the energy required to cook one hot dog is 60.7 kJ. If the rate at which energy is supplied is unchanged, how long will it take to cook three hot dogs simultaneously? Number n Units v
