Ok, I solved it finally using mesh analysis. Anyway, going back to your first post. You found I2 = -1/2*I. What does '-' sign tells us ? That the real current is reversed ? But how can it be if we have only one current source and the current should flow as my arrows on schematic indicates.
Thanks
The direction of mesh current is arbitrary and can be chosen freely. So I deliberately choosen as shown in first post just to practice this method. Now can you tell me why I fail with my mesh equations ?
PS: you did this with Kirchoff laws, and it's ok, I did it also, but what abut mesh - current ?
Hello, I am getting headache trying to solve this simple circuit o.0
I set mesh and traditional currents as follows
Now for the left mesh current:
-Vx + 10i1 + 4Vx + 15(i1-i2) = 0 -> 10i1 - 15i2 = 0
(assuming Vx = -5i1)
and for the right mesh:
15(i2-i1) = 0 -> i1 = i2
and here is the...
Hello, I have simple circuit shown below, my question is how to find i0 and v0 plus why there are "+" and "-" signs next to 8 Ohm resistor ? Resistors doesn't have polarity, so what it means ?
Thanks for help.
Hello I would like to study deeply about wireless technology, my goal is to understand theory and practice about making my own electronic transmitter and receiver from electrons up ;)
Can you recommend books on subject ?
Hello,
I have some difficulties trying to understand the debug process of microcontroller. What kind of micro. and programmer I need to be able to debug program. What I mean by debug is at least have possibility to print out variable values.
As for now I have atmega8, is it possible to debug...
huh it looks like space between int and main caused the problem o.0 I am strating to doubt if Atmel studio is good IDE.
PS: what this line define: #define F_CPU 1000000UL ??
Thanks.

One more issue, this is my first time with AVR, I use Atmega8, Atmel studio + avrdude...
Hello, I try to complie (using atmel studio 6 ) example C code for led blinking:
#define F_CPU 1000000UL
#include <avr/io.h>
#include <util/delay.h>
int
main (void)
{
DDRB |= _BV(DDB0);
while(1)
{
PORTB ^= _BV(PB0);
_delay_ms(500);
}
}
I get atmel studio error: Error 1 'DDB0'...
Hello, as everybody I have couple of old LI batteries, I wonder how to give them a new life in my electronics projects.
Those batteries have 3/4 pins, I googled for datasheet of them but no luck ;( How to detect which pi is what and most importantly how to charge it ?
If battery has 3.7 V output...
Hello, I am looking for circuit which is able to detect voltage changes without help from chips. Let's say I want to turn on diodes accordingly to voltage magnitude, voltage is low - one of four diodes is on . With help of microcontroller and ADC it is simple, can be done without micro... ?
Thanks.
