Another method of solving the circuit of Figure P2.24 is to start by assuming that v₂=1 V. Accordingly, we work backward toward the source, using Ohm’s law, KCL, and KVL to find the value of v_s
Since we know that v₂
is proportional to the value of v_s; and since we have found the value of vs that produces v₂=1 V we can calculate the value of v₂
that results when v_s=12 V. Solve for v₂
by using this method.
