Hi all,
I just have two questions about this circuit diagram. 1. The current labelled i3 next to the 80V source - is i3 through 80V source, or through the 4kohm resistor? I can't decide if the authors meant it to be through the source or the resistor. Two of the other resistors have labelled currents, except the 1kohm resistor. Which leads to 2. Is the current through the top branch containing the 1kohm resistor 10mA, or 10mA -i3? If so, then I can determine the mesh currents.
Thanks. The problem is to find the power dissipated in the 1kohm resistor, so that's why I am trying the determine the current through it.
