Find the output current $i_o$ in the circuit shown below using superposition, where $v_s = 32cos(9t)V$.
Given: $i_{o1}$ is the value of phasor $i_o$ when only 20 V source is on and $i_{o2}$ is its value with $v_s(t)$ on only.
The current $i_{o1} = \text{________} A$ (Calculate to 2 decimal places)
The current $i_{o2} = I_{o2}\angle\theta$ A, where:
$I_{o2} = \text{________} A$ (Calculate to 2 decimal places)
$\theta = \text{________} deg$ (Calculate to 2 decimal places)
