In the given DC circuit, a) Compute the open-circuit voltage (Voc) at terminals a-b by using node voltage method. b) Compute the short-circuit current (Isc) at terminals a-b by using mesh current method. c) Calculate the Thvenin (or Norton) equivalent resistance. (R-Voc/Isc) d) Draw the Thvenin and Norton equivalent circuits. e) If a load is connected to terminals a-b, calculate the value of the load resistance for the maximum power transfer. Find the maximum power that can be delivered to the load. y=9 0.5y y 0 7A www-a 12 V
