A 17.0 μF capacitor is charged by a 130.0 V power supply, then disconnected from the power and connected in series with a 0.280 mH inductor. Calculate the energy stored in the inductor at  t  = 1.30  ms .

A battery providing emf V is connected in series to a resistor R and an inductor L, and left until the current reaches a constant value. (a) What is the energy stored in the inductor in terms of V, R and L? Then, at t = 0, the battery is suddenly removed, so that only the inductor and resistor are left connected to each other in a closed circuit. (b) Derive an expression for the energy stored in the inductor in the new circuit without the battery. Sketch your expression as a function of time. (c) How long does it take for the energy stored in the inductor to decay to 1/9 of the initial value that you found in part (a)?

A 24.0-V battery is connected in series with a resistor and an inductor, with R = 9.20N and L = 9.20 H, respectively. (a) Find the energy stored in the inductor when the current reaches its maximum value. (b) Find the energy stored in the inductor at an instant that is a time interval of one time constant after the switch is closed.

Help A V = 86-V source is connected in series with an R = 1.8-kΩ resistor and an L = 28-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. After the current decreases to 53 % of its maximum value, the battery is reconnected into the circuit by reversing the switch. 1) At what value of the time t, in milliseconds, does the current reach 77 % of its maximum?  2)  How much energy, in millijoules, is supplied in total by the battery, both in initially bringing the current to maximum and in bringing the current back to the 77 % level from 53 %? Ignore energy dissipated in the resistor during those processes.

A 19.0 mH inductor, an 6.00 Ω resistor, and a 9.00 V battery are connected in series. The switch is closed at t = 0.  ( h) What is the maximum energy stored in the inductor?
