Transcription: The topic for this discussion is nodal analysis. A junction point which has two or more electrical currents is termed a node. The basis for this type of analysis involves current sources and therefore KCL equations that can be used to compute the nodal currents. Current sources driving current into a node are positive, whereas current sources driving current out of a node are negative. In the example shown, assuming the voltage at point A is positive with respect to ground, Using KCL at node A, we have minus five milliamps plus the quantity minus 10 milliamps equal to V one divided by one K pl ...
