4.1.Part A: Ohm's law
This part aims at checking and proving Ohm's law. Using the fixed 5 V output from the power supply,
the 1k, 2k2 and 5k resistors, and considering all the possible unique circuit combinations with
these 3 resistors only, conduct the followings:
1. Before the lab session and manually
a) design and manually sketch your various circuits using the fixed 5 V power supply (i.e. put
the resistors in various parallel or series combinations),
b) calculate the current (immediately after the power supply) for all your circuits and find the
current and the power dissipated in each of the 3 resistors,
c) rank the circuits from maximum to minimum current observed immediately after the power
supply, and
d) prepare your report and have it with you electronically at the time of your lab session.
2. Before the lab session, and using the LushProjects simulator (see above URL)
a) make simulation files and simulate all your circuits,
b) check and compare the results with the manual…

- Example 4.7 Find v, in Fig. 4.20 using source transformation. Solution: The circuit in Fig. 4.20 involves a voltage-controlled dependent current source. We transform this dependent current source as well as the 6-V 0.25v independent voltage source as shown in Fig. 4.21(a). The 18-V voltage source is not transformed because it is not connected in series with any resistor. The two 2-N resistors in parallel combine to give a 1-N resistor, which is in parallel with the 3-A current source. The current source is transformed to a voltage source as shown in Fig. 4.21(b). Notice that the terminals for Uy are intact.
