5.2 Traditional Differential Equations Approach
However, before proceeding, note that the circuit’s current response to the sinusoidal voltage source is
i(t) » 1.49cos(3t - 63.43°) A.
How do the voltage source and current response differ mathematically?
They differ by only two numbers¾magnitude (10 V. versus 1.49 A.) and phase angle (0° versus -63.43°)!
