Easy# Parallel and Series Resistors

EANDM-YHYU8R

The circuit diagram below shows a battery with three resistors . The values for the voltage as resistances are: $\Delta V = 10.0 \: \rm V$, $R_1 = 100 \: \Omega$, $R_2 = 200 \: \Omega$, and $R_3 = 300 \: \Omega$.

Determine the current that flows in $R_3$.
