Question: review constants part a the voltage applied to the circuit...

Question details

Review Constants Part A The voltage applied to the circuit shown in (Figure 1) att-0 is 20 cos(800t t 25*) V, where t is in seconds. The circuit resistance is 80 Ω and the initial current in the 75 mH inductor is zero. Select the correct expression for i(tr0 View Available Hint(s) o i(t)-196e 106t 200 cos(800t 11.9) mA ()19Ge100 cos(80025) mA i(t) -196e 200cos(800t 25°) mA ()900( 11.9) mA Correct Here we leam how to find the correct expression for i(t) for t0 in an RL circuit excited by a sinusoidal voltage source. Part B Select the correct expression for the transient component of i(L).
