Hi, i'm having a test on electricity next week so i just wanted to ask
if some of u guys have a web site or some reference to read
about ohm law formula and some expentions for:
* Watt
* Resistance
* Voltage
* Current
in parralel/serial and JOINED circuit.
and also about calculation JOINED circuit with 3 power sources and common resistors.
like :
e1 = I1(r1+r2+r3) - I2(r3) - I3(r2)
e2 = -I1(r1) + I2(x,x,x) - I3(x)
....
thanks!

Kirchoff would be a word to google with...Morbid said:...and also about calculation JOINED circuit with 3 power sources and common resistors.
Superposition is quite simple. Look at current/voltage sources one at a time. Replace other current sources with an open-circuit, and replace other voltage sources with a short-circuit. Solve for these simpler circuits individually, and when you get whatever value you are looking for, add the simple answers together to get the total value.
Here is an example I found in google:
Superposition example
Hope it helps
