The transformer secondary is now connected to a purely resistive load drawing 50A. Calculate:a) the total resistance and leakage reactance values referred to the secondary (Rt2 and Xt2),b) the output voltage,c) the output power, VA and Vars,d) the iron loss, primary copper loss and secondary copper loss,e) the efficiency,f) the input current in magnitude and phase (wrt the supply voltage).
Design a 4-bit circuit for 2s-complement, base on the formula below, using only inverters, 2 input AND gates and 2 input OR gates. Design your circuit to be as fast as possible. What is the worst-case propagation delay for this circuit
