finally.

View whole wall

revise PLEASE!!!!!

the killer subject of CIRCUIT THEORY..

CIRCUIT THEORY~

supernode

Supernode

A "supernode" is assumed sometimes in circuit theory to solve a circuit, whereby a voltage source on a wire is viewed as a point source voltage in relation to other point voltages located at various nodes in the circuit, relative to a ground node assigned a zero charge.

A supernode can also refer to Nodal analysis which is a circuit analysis technique used in Electrical Engieering. In general engineering circuit analysis, supernode is that in which voltage source is in between the two nodes.

Example :

The green shading shows the supernode. The sum of the currents leaving the supernode must sum to zero - for the same reason that the sum of the currents leaving a node sum to zero - conservation of charge!

Write the KCL equations for the entire super node:
Ix + Iy + Iz = 0.
But Ix = (Vy -Vx)/Rx , Iy = Vy / Ry , Iz = Vz / Rz= (Vy - V2)/ Rz
And the KCL equation for the supernode becomes:
(Vy -Vx)/Rx + Vy / Ry + (Vy - V2)/ Rz = 0.

And, for this circuit that is the one independent KCL equation that can be written (unless you choose to keep Vz as your unknown, but there is still only one equation.) That means writing this in the standard form, we would have:
(1/Rx + 1 / Ry + 1/ Rz)Vy - Vx/Rx = V2/ Rz
The coefficient of Vy is the sum of the conductances connected to the supernode, the source appears on the right hand side, and the negative reciprocal of the shared resistor shows up just where we might expect it.

ORIgami....:)

ORiGAMi????urmmm..tak pernah langsung terlintas di akal fikiran.kalau ade pun just untuk habiskan kertas yang memang berlambak dalam bilik (*sebab student banyak guna kertas..hiii~)..one day,i got a call from my beloved sister.AND yu know what???? "faza,aku nak bertunang dah.".yeeha~~~~ and you as a sister you must help me to make ORIGAMI PAPER CRANE...."
for what???for my sister mini pelamin.
go YOUTUBE.COM....search>>>>HOW TO MAKE PAPER CRANE....and all my friends helps a LOTTTT...thank you guys.love u <3
last words,ORIGAMI TU COMEL....:)
