- A 3.5 mH inductor and a 4.5 mH inductor are connected in series and a time varying current is established in them. When the total emf of the combination is 16 V, what is the emf of the larger inductor?A V = 86-V source is connected in series with an R = 1.8-kΩ resistor and an L = 26-H inductor and the current is allowed to reach maximum. At time t = 0 a switch is thrown that disconnects the voltage source but leaves the resistor and the inductor connected in their own circuit. 1) How much time, in milliseconds, is needed for the current in the circuit to drop to 12 % of its value at t = 0? 2) How much energy, in millijoules, does the circuit dissipate during that time?The circuit shown consists of three resistors and two inductors. The resistors have resistances of R1 = 19 Ω, R2 = 11 Ω, and R3 = 11 Ω. The inductors have inductances of L1 = 0.75 H and L2 = 1.5 H. (a) Calculate the equivalent resistance of the parallel resistor combination in Ω. (b) Calculate the total resistance of the circuit in Ω. (c) Calculate the equivalent inductance of the parallel inductors in H. (d) Find the time constant of the circuit in s.
