3. a) Under DC conditions, determine the current (ix) for the circuit in figure 2. ww 16 ΚΩ m 2μH m 6 дн ww 7 ΚΩ 10 V · 4.7 ΚΩ 4.7 ΚΩ (9 marks) Figure 2 b) The following graph figure 3 is showing the relationship between the marks) amplitude and the time of damping harmonic oscillator system for three different damping constants (B). The damping constant (B), describes the damping strength and how apparent friction is in the system. From this standpoint, explain the Oscillations in a damped harmonic oscillator for different damping constants when (B-0.3, B=1 and ẞ=7) in the system.
