Explanation Given Information: The given circuit is shown below. The given symptom is that the voltmeter reading is 5.45 V and ammeter reading is too low. Consider the given circuit if resistance R 1 is open, then there is no flow of current through the circuit. Thus, ammeter will indicate zero and voltmeter wil also indicate zero reading. Therefore cause R 1 is open not matches with the symptom. If R 2 is open, then the current in the circuit will be , I = V s R 1 + R 2 = 12 V 27 k Ω = 0.44 mA So the ammeter reading will be 0.44 mA . Now check voltmeter reading. Voltage across resistor R 3 will be, V R 3 = R 3 R 1 + R 3 × V s = 15 k Ω 27 k Ω × 12 V = 6.67 V So voltmeter reading is 6
