Rangkaian ekivalen Thevenin adalah rangkaian ekivalen dari B 1, R 1, R 3, dan B 2 yang “terlihat”dari dua titik dimana resistor beban (R 2) terhubung. Rangkaian ekivalen Thevenin, bila diturunkan dengan benar, akan mempunyai sifat yang sama dengan rangkaian aslinya yang terdiri dari B 1, R 1, R 3, dan B 2.
R1=1k R2=1k R3=2k R4=2k R5=3k R6=3k R7=3k
1. Short AB, as shown in Figure 3 - 2 (a). Use mesh analysis tocalculate the voltage
across each resistor and the current through AB.
2. Leave AB open, as shown in Figure 3 - 2 (b). Use nodal analysisto calculate the
voltage across each resistor and that across AB.
3. Find Thevenin’s and Norton’s Equivalent (Voc, Isc and Rt) usingthe results from step 1
and 2.
4. If a resistor is connected between nodes A and B, use Thevenin’stheorem to calculate
the current through this resistor using the following values: 1 k?,2.2 k? and 4.7 k?.
5. Leave AB open. Find the voltage across AB caused by E1 only.In order to do so, E2 and
E3 need to be set to zero by simply replacing each of them with awire (short). Repeat
this step and find the VAB caused by E2 only and E3 only. Verifythat the sum of these
three voltages found using each source individually equals to thatfound in step 2.
