The voltage across a 250 mH inductor is v(t) = 25te Volts fort 20. v(t) = 0 for t <0. At t=0,assume that i(0) = 0 Amps. a) Find the current through the inductor for t> 0 (assume the passive sign convention, see page 761 of the text for a table of integrals) b) Find the power at the terminals of the inductor at t = 40 ms (i.e. p(t)-50 ms) c) Is the inductor absorbing or delivering power at t = 40 ms? (hint it is absorbing If answer in b is positive) d) How much energy is stored in the inductor at time t = 40 ms? The voltage across a 250 mH inductor is v(t) = 25te Volts fort 20. v(t) = 0 for t <0.
