In summary, I2 and Vab are variables used to represent electric current and voltage in Eq.3, which is used to calculate power dissipation in a circuit. Finding these values is important for understanding the behavior and efficiency of the circuit. To solve Eq.3, you can use Ohm's Law and Kirchhoff's Voltage Law. Common mistakes when solving Eq.3 include unit conversions, incorrect values, and misapplication of laws. Other methods, such as Thevenin's Theorem or Norton's Theorem, can also be used, but may require more advanced knowledge.

Hi, :smile:

I need to find I2 and Vab. You will find all the details in the provided link: http://img690.imageshack.us/img690/9260/i2vab.jpg

I am sure my answers are wrong because when I put the values in eq.3 it is not satisfied. But I have failed to see where I go wrong. Please help me with it. Many thanks.

Cheers
