Figure P1.27 shows an ammeter (AM) and voltmeter (VM) connected to measure thecurrent and voltage, respectively, for circuit element A. When current actually enters the + terminalof the ammeter, the reading is positive, and when current leaves the + terminalreading is negative. If the actual voltage polarity is positive at the + terminal of the VM, thereading is positive; otherwise, it is negative. (Actually, for the connection shown, the ammeterreads the sum of the current in element A and the very small current taken by the voltmeter. Forpurposes of this problem, assume that the current taken by the voltmeter is negligible.)
