The current in the series circuit across a 9.0 V potential difference is determined as 0.333 A.
The current in the series circuit is determined by applying ohms law as shown below;
V = IR
where;
R = 12 Ω + 15 Ω = 27 Ω
I = V/R
I = 9/27
I = 0.333 A
Thus, the current in the series circuit across a 9.0 V potential difference is determined as 0.333 A.
