To find the source voltage $ V_s $, we use Ohm's Law, which states $ V = IR $, where $ V $ is the voltage, $ I $ is the current, and $ R $ is the resistance. In this series circuit, the total resistance $ R_{total} $ is the sum of $ R_1 $ and $ R_2 $:

$$ R_{total} = R_1 + R_2 = 2 \Omega + 9.2 \Omega = 11.2 \Omega. $$

Given the current $ i = 1.3 $ Amps, the source voltage $ V_s $ is:

$$ V_s = i \times R_{total} = 1.3 \times 11.2 = 14.56 \text{ Volts}. $$

Thus, $ V_s $ is 14.56 Volts to two decimal places.
