A first order circuit is given according to the following circuit schema. The switch is on position 1 for a sufficiently long period of time and steady state conditions are esthablished. At the time t=0, the switch is taken to the position 2. a) What does "sufficiently long period of time" mean? Do we have a measure for the duration? If you can give a quantitative value, please, calcuate it. Please, calculate: b) the time dependent decay of the voltage vc(t) across the capacitors C₁ and C₂, and sketch a rough graph of the vc (t) versus time indicating important points on it, c) the current iR2(t) through the resistor R₂, d) the dissipated power across R2, e) the total dissipated energy over R2. f) What is the portion of the energy dissipated on R₂ in relation to the total energy stored on the capacitors at the time t=0? g) What is the value of IRO after switching to position 2? The following values are given for the circuit elements and for Vo: R₁ = 15 KQ; R₁ = 5 km; R₂ = 30 km; R₂ = 60 km; C₁ = 1,2 uF; C₂ = 800 nF; V₁ = 60V; t=0 21 R₁ IRO İR 2 (t) ic(t) R₁ 11 Vo vc(t) + C₁ C₂ R3 R₂
