While changing sources what are the things i need to consider. Like in the question if i need to change 10A current source in parrallel with 10 ohm to voltage source how can i change it. And also 20A in parallel with 20 ohm resistor.

Do it normally place the 10-ohm resistor in series with a voltage source I*R.

And also 20A in parallel with 20 ohm resistor.

No, what about 30 ohm + 40 ohm? They are also in parallel with 20A current source.

 

I was wondering about the sign in new voltage source. And are 1 and 2 same in my new equivalent circuit?

 

The voltage source polarity will be determined by the current source direction.

And are 1 and 2 same in my new equivalent circuit?

Yor equivalent circuit is wrong. Why the 10-ohm resistor is not in series with the 100V voltage source ?

Oh that was a silly mistake, yea i know i calculated voltage using 10 ohm but wrote 20 ohm, but any way thats how its changed right?

 

Your 100V source has a wrong polarity

Oh, thanks.
