A circuit is composed of a coil having N turns and area A. Its leads are connected to a combination of resistors, as shown in (Figure 1). All three resistors have the same resistance R. The coil is placed in a perpendicular magnetic field B₀, and then the field is uniformly reduced to zero over a time period ?. During the period in which the field is being ramped down, the magnitude of the potential difference across the resistor R₃ is measured to be V. Determine the value of V. Express your answer in terms of some, all, or none of the variables B₀, A, N, R, and ?.
