Below is a circuit diagram. Each of the L; are different inductors(each having and induction of 1 henry), while the Rị is a resistor( with a resistance of 4 ohms). We will make the following assumption: the input voltage V (t) = 0 when t2 0. Below is the circuit diagram: ell L2 1H Loop 2 R1 Loop 1 L2 1H l L3 1H 2 Calculations For the circuit above, find the following: • Set up the system of differential equations. • Find the general solution for a given time t. • Find the exact solution if you are given that Io = . l +

c) Using minimum number of components, design a voltage divider which can deliver 1 W at 100V, 2W at -50V and 1.6W at -80V. The voltage source has an internal resistance of 200 Q and supplies a current of 100mA. What is the open - circuit voltage of the voltage source? All resistance in ohm.

In an electrical circuit four resistors are connected in parallel and their equivalent resistance is 50ohms. Find the value of each resistors if the currents through each impedance are 0.8, 0.4, 0.6 and 0.2 ampere.
