An experimental circuit is shown below. All meters and batteries are ideal. When the 18.0 Ω resistor is plucked out (creating a gap), the voltmeter displays 12.0 V. Determine the ammeter reading when the 18.0 Ω is replaced with a low resistance shunt. 

• A. 0.817 A
• B. 1.33 A
• C. 0.729 A
• D. 1.12 A
• E. 0.915

Answer: (B)
