7. The Thevenin equivalent voltage for a given circuit is found by (a) shorting the output terminals (b) opening the output terminals (c) shorting the voltage source (d) removing the voltage source and replacing it with a short 8. A certain circuit produces 15 V across its open output terminals, and when a 10 k load is con- nected across its output terminals, it produces 12 V. The Thevenin equivalent for this circuit is (a) 15 V in series with 10 k (b) 12 V in series with 10 k (c) 12 V in series with 2.5 k (d) 15 V in series with 2.5 k 9. Maximum power is transferred from a source to a load when (a) the load resistance is very large (b) the load resistance is very small (c) the load resistance is twice the source resistance (d) the load resistance equals the source resistance 10. For the circuit described in Question 8, maximum power is transferred to a (b) 2.5 ΚΩ load (a) 10 ΚΩ load (c) an infinitely large resistance load
