Calculate α, ω0, s1, and s2 for a source-free parallel RLC circuit if (i) R = 4 Ω, L = 2.22 H, and C = 12.5 mF; (ii) L = 1 nH, C = 1 pF, and R is 1% of the value required to make the circuit underdamped. (iii) Calculate the damping ratio for the circuits of parts (i) and (ii

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct
