The question: Suppose point A is grounded (V = 0) in Figure 21-36, in which script e = 16 V and R = 11 . Find the potential at points B and C. Here is the diagram: http://www.webassign.net/walker/21-35alt.gif I'm pretty sure that I have to use Kirchhoff's rules in order to solve this problem, but I'm afraid that I've been reading them over and over and don't completely understand them. Especially with this 'grounded' stuff. Does that mean that I just ignore that part of the circuit, where 6.2 and 11 ohm are? I guess I need a little bit of guidance in how to start solving this.
