# Homework Help: Finding Thevenins equivlant using his thereom and nortons

Hi there,
See attached for original circuit.

Basically I need to find thevenins equivalent of the network.

My attempt:-
To find the resistor equivalent
First of all I replaced all voltage sources with shorts, and replaced all current sources with open circuits.

This left me with 16 ohm (10+6),24 ohm and, 1.777 all in parallel.

The sum of the resistors gives the equivalent resistance of 1.499 ohm.

Now this is the part where I don't know what to do next. Do I convert the circuit so the sources are voltage sources?

Any help or guidance most appreciated

Any guidance much appreciated!

Hi, I suggest that you do the transformation so all the voltage sources and current sources can be unite into one. This is just a suggestion.Please correct me if I'm wrong. Thank you!

You need to find the open-circuit voltage across A and B with all the sources activated. This will be the Thevenin equivalent voltage.

I believe using source transformations would have also worked...
