Can you rearrange it so that it consists of simple series or parallel combinations of resistors? You should find that you cannot. (If the 10.0 V battery were removed and replaced by a wire from b to the 6.0 N resistor, the circuit would consist of only series and parallel combinations.) Categorize We cannot simplify the circuit by the rules associated with combining resistances in series and in parallel. Therefore, this problem is one in which we must use ---Select--- Analyze We arbitrarily choose the directions of the currents as labeled in the figure.
