(A) The resistors are connected in series,so the equivalent resistance $R_{eq}$ is:$R_{eq} = 2 \ \Omega + 3 \ \Omega + 5 \ \Omega = 10 \ \Omega$The current $i$ flowing through the circuit is given by Ohm's law:$i = \frac{V}{R_{eq}} = \frac{2 \ V}{10 \ \Omega} = 0.2 \ A$The potential difference $V'$ across the $3 \ \Omega$ resistor is:$V' = i \times R = 0.2 \ A \times 3 \ \Omega = 0.6 \ V$
