Determine the Vo in the
circuit of the following
figure :

Vo = 4.5 [V]

Explanation:

In order to calculate this Vo voltage, we must first calculate the current through the entire circuit. For this, we perform a sum of voltages equal to zero.

ΣV = 0

We again perform a sum of voltages equal to zero but this time we do not include the voltage source of 3V as well as the resistance of 2[ohm]. It is as if the circuit is open between the ports of Vo.

ΣV = 0

correct it is c.) b b
