EBN111 2016-June Exam 14 Question 2.5 [4] a) What is the maximum power, P max , which can be delivered to a load if the load is connected to a circuit with a Norton equivalent current of 5.5 A and Norton equivalent resistance of 60 ? b) For the circuit below, what is the power P which can be delivered to a 50 load if the load is connected between terminals a and b ? (The Thevenin equivalent voltage of the circuit below is 30 V. The 50 load is not shown in the circuit.) Vraag 2.5 [4] a) Wat is die maksimum drywing, P max , wat aan ‘n las voorsien kan word indien die las aan ‘n kringbaan gekoppel word met ‘n Norton ekwivalente stroom van 5.5 A en ‘n Norton ekwivalente weerstand van 60 ? b) Vir onderstaande kringbaan, wat is die drywing P wat aan ‘n 50 las voorsien kan word indien die las tussen terminale a en b gekoppel word? (Die Thevenin ekwivalente spanning is 30 V. Die 50 word nie in die kringbaan aangedui nie.)
