A student wants to measure the electric potential difderence across the resistor R2 for the circuit below.

I've got a circuit with two batteries, and Kirchoff's laws give me the equations i₁ + 12 = 13 V₁₁R₁ - 13R3 = 0 V2-12R2 - 13R3 = 0 The circuit has R₁ = 109, R₂ = 209, and R3 = 409. The first battery has a fixed voltage V₁ = 35V, but the second battery can be adjusted to anything between 20V and 60V. Write a .m function file called myCircuit.m that takes V₂ as an input and produces an array containing i₁, i2, and i3 as an output. That is, the output should be a single (vector-valued) variable. The function must use the backslash operator to solve the linear system.

The figure shows a circuit. The switch S can be closed on either point A or C, but not both at the same time. Use the following quantities: V₁ = V₂ = 12 V R₁ = R4 = 1.00 R₂ = R3 = 2.00 [ R 4 O 2A O 6 A O 1 A O 12 A S О ЗА R₁ Determine the current through R₁ when the switch S is closed on A. W K Bm! B
