- 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?I think its physics questionA 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?
