1. Given the forcing function:
v(t) = 60e^{-2t} \cos(4t + 10^\circ)
2. The expression for the forced response is:
i(t) = I_me^{-2t} \cos(4t + \phi)
3. By comparing the two expressions:
60e^{-2t} \cos(4t + 10^\circ) \quad \text{and} \quad I_me^{-2t} \cos(4t + \phi)
we can determine:
I_m = 60 \quad \text{and} \quad \phi = 10^\circ
4. Thus, the values are:
I_m = 60
\phi = 10^\circ
2. The expression for the forced response is:
3. By comparing the two expressions:
we can determine:
4. Thus, the values are:
