You are given the circuit shown below a Find the opencircuit

You are given the circuit shown below. a). Find the open-circuit voltage seen looking into the terminals a-b. b). Find the Thevenin equivalent resistance seen looking into the terminals a-b. c) Sketch the final thevenin equivalent circuit showing both the resistance value and the open-circuit voltage.

Solution

to find the thevenence equavalent resistance make all the voltage sources are shortcircuit and current sources are open circuit.

here 4ohms resistor and 4ohms resistor are in parller.

Zab=2+2=4ohms.
