Exercise 2 A. We consider the circuit given by figure 1 1. Determine the impedance matrix as well as the corresponding electrical model. 2. Determine the admittance matrix as well as the corresponding electrical model. S B. A Wheatstone bridge bolometer is an instrument which makes it possible to measure the temperature T of a body, from the variation of the resistance of the ohmic conductor which is put in contact with this body. Initially, the four resistors are equal to R and the bridge, supplied by a voltage source of f.e.m Ek, is balanced. Figure 2 1/2 Ve le с Figure 1 R₁ R₂ A A (B) EK R N Ri R₂ Is Vs Q
