5.45 Given the linear circuit in Fig. P5.45,

it is known that when a 2-k! load is

connected to the terminals A - B , the

load current is 10 mA. If a 10-k! load

is connected to the terminals, the load

current is 6 mA. Find the current in a

20-k! load.

5.46 If an 8-k! load is connected to

the terminals of the network in

Fig. P5.46, VAB = 16 V. If a 2-k!

load is connected to the terminals,

VAB = 8 V. Find VAB if a 20-k!

load is connected to the terminals.

E5.4 Find V0 in the circuit in Fig. E5.2 using both Thévenin's and

Norton's theorems. When deriving the Norton equivalent circuit,

break the network to the left of the 2-k! resistor. Why?
