7. Note: The letter "i" blue icon means "The Tolerance is 1 in the 3rd significant digit."

When resistors 1 and 2 are connected in series, the equivalent resistance is 21.4 0. When they are connected in parallel, the equivalent resistance is 4.47 0. What are (a) the smaller resistance and {b} the larger resistance of these two resistors? (a) Number n Units v (b) Number n Units v In the gure R1 = 6.24 0. R2 = 18.7 E), and the ideal battery has emf a = 10.2 V. (a) What is the magnitude of current i1? (b) How much energy is dissipated by all four resistors in 2.59 min? {a} Number n Units v {b} Number n Units v
