Answer
The electric potential at point A is $~~3.82~V$
Work Step by Step
We found that the current through resistance 3 is $38.2~mA$
To find the electric potential at point A, we can move through the circuit from ground, across resistance 1, to point A:
$V_A = 0+(100~\Omega)(38.2~mA)$
$V_A = 3.82~V$
The electric potential at point A is $~~3.82~V$
