Question

Please look at the circuit:

Look at how chegged added the 2 parallel resistors. They put the 12 ohm resistor on the right side, while I put it on the left side.

1. Is this the same thing?

2. How do I know which side of the current source to put the combined parallel resistors on?

Now look at how chegg converted the parallel current and resistor to a series voltage source and resistor:

3. "What" tells you to put the voltage source and 12 ohm resistor at the bottom versus at the middle line?

4. Also what tells you to put the voltage source on the left side and the 12 ohm resistor on the right side versus putting the voltage source on the right side and the 12 ohm resistor on the left side?

Please ANSWER all 4 questions so I can understand it all.

Dont just answer one or 2.

Thanks!

Explanation / Answer

1)Yes chegg did the right thing for explanation see the no.3)

2)check like this
if resistors, current sources should be in parallel in between that no other sources or resistance must not present then pick that circuit and simplify that

3)it was source transformation technique

in that if any current source is parallel with resistor then the VOLTAGE = IR =(PARALLEL CURRENT SOURCE * PARALLEL RESISTANCE)= SERIES VOLTAGE WITH A RESISTOR AS SHOWN IN CHEGG ANSWER.

4)THEN here no problem of putting the voltage source on left or right we can put any where because whether we put the voltage left or right to the resistor ,both are in series so current is same no problem
