2.2. Find out a Thevenin/Norton equivalent circuit by following the below steps (40 pts). Uslov R₁ = 1052 w+! Ri R₂ www R₂ 0 R₂=452 R3=25 ( vtha ( In, Rth 201 Thevenin or Norton (a) Open-circuit test: Let's calculate Voc (open-circuit voltage that occurs between the two terminals) first. Find out Voc by treating Voc as a node voltage and applying KCL & a voltage-divider rule. To receive the full credit, clearly specify or indicate in the circuit where is Voc. (15 pts) (b) Short-circuit test: Next, find out Isc (short-circuit current that flows between the two terminals) by knowing that the resistance of an ideal current source is very high and there is no current flow to R₂ and R3 resistors. To receive the full credit, clearly specify or indicate in the circuit where is Isc (15 pts) (c) Equivalent circuits: Draw both Thevenin and Norton equivalent circuits by using Voc obtained from (a), Is obtained from (b), and the relation Vth (Thevenin voltage) = ln (Norton current) *Rth (Thevenin resistance).
