Given resistors R₁ = 1 kN, R₂ = 2 kn, and inductor L₁ = 5 H. The voltage source is set to V₁ = 10V. The switch S₁ is initially closed long enough to ensure the circuit reached steady state. At time t = 0 seconds, the switch S₁ opened. Calculate how much energy dissipated by the resistor R₂ for t≥ 0 seconds.
