Solution:

We shall convert the current source into its equivalent voltage source and
also take away the 5 Ω resistor from the terminals A and B. We will calculate

the V across terminals AB.

Using kirchhoff’s voltage equation in the loop as shown above we write

Voltage across point S and R is calculated by moving upwords from point S
to point R.

Considering the voltage rise we get,
