![]() The reading of the voltmeter will be 2.88 V. According to Ohm's law, V = IR, where, Potential difference, V = 6 V Current flowing through the circuit/resistors = I Resistance of the circuit, R = 5 + 8 + 12 = 25 ohm I = 0.24 A Potential difference across 12 ohm resistor = V I Current flowing through the 12 ohm resistor, I = 0.24 A Therefore, using Ohm's law, we obtain V 1 = IR = 0.24 x 12 = 2.88 V Therefore, the reading of the ammeter will be 0.24 A. ![]() Concept Insight:- Ohm's law can be used to obtain the readings of ammeter and voltmeter. ![]() To measure the potential difference across the 12 ohm resistor, a voltmeter should be connected in parallel to this resistor, as shown in the following figure. ![]() To measure the current flowing through the resistors, an ammeter should be connected in the circuit in series with the resistors. ![]()
