Determine the mathematical model equations for the electrical circuit shown in figure 2. The circuit is consisting of two resistors, two inductors and a capacitor. A voltage Va is applied to the circuit. Derive an expression for the mathematical model of the following circuit. R1 L2 i1 13 14 16 + O- i2 i5 R2 L1 Va C Figure (2) the electrical circuit u

(a) Use Ohm's Law to derive an expression relating Vout to Vin using the values of the two resistors. For this calculation, assume that you have no load attached (i.e. RL → xx). Make sure to explain in words each step you take. Hint: Vout is just the voltage drop across R2. You can draw in a battery with AV = Vin if that helps you set up the relationships. R1 Vin R2 Vout (O Vin- Your answer should be in the form, Vout The term in parentheses is called the gain of the divider, or the divider ratio. in· ww
