2. For each circuit, find the currents through each element, as well as the diode voltage. Express these answers to three decimal places in V or mA, and use the exponential model for the diode, Is = 10-15 A. 10V

Solve only 4 please

Scnerio: You have to design a controller for a split Air conditioner. The Air conditioner can go into 4 states. They are Heat, cold, dry, auto. The controller receives an input from the user and for every input it changes the state in the sequence – Heat -> cold -> dry ->auto -> Heat. Note Your also have to make  state diagram, state transition table, and the circuit acording to the design. FOR 4 states I  GUESS flip flops Iis used for circut diagram. solve as soon as possible
