Final answer:
The question addresses the calculation of the current through a resistor in a circuit containing an ideal op amp, falling under the subject of Physics, specifically within the college-level electricity and circuit course content. The classic Ohm's Law is applied to determine the current amplitude with a given resistor value and maximum voltage.
Step-by-step explanation:
Understanding the Circuit with an Op Amp
The student's question involves an operational amplifier (op amp) in a circuit and the calculation of the current through a resistor. This question falls within the field of Physics, specifically in the area of electricity and circuits, which is typically covered in college-level courses.
In this case, the student asks to determine the amplitude of the current in a circuit where R (presumably R2) is specified to be 100 Ohms, using the ampere-volt data provided. The current I through the resistor can be calculated using Ohm's Law, which states that I = V/R. For the maximum voltage of 10 V, the current amplitude would be Io = 10 V / 100 Ω = 0.10 A.
For the specific values provided (va = 0.49 V, vb = -0.32 V, and R2 = 10 Ω), the question is incomplete as it does not specify the complete circuit diagram or the exact calculation required for this set of parameters. Without this information or the relation of these voltages to the operation of the circuit, a specific answer cannot be computed.
