Two Resistors with Resistances Of $5.0 \Omega$ And $9.0 \Omega$ Are Connected in Parallel

Short Answer

Two resistors with resistances of $5.0 \Omega$ and $9.0 \Omega$ are connected in parallel. A 4.0- $\Omega$ resistor is then connected in series with this parallel combination. An ideal 6.0-V battery is then connected across the series-parallel combination. What is the current through (a) the $4.0 - \Omega$ resistor and (b) the $5.0 - \Omega$ resistor?
