The problem is asking for the current through resistor $R_5$ in the given circuit, where we have five resistors and a battery with a given voltage. To calculate the current, we need to first determine the equivalent resistance of the circuit.

Steps to approach the problem:

1. Identify the resistors’ connections: The resistors $R_1, R_2, R_3, R_4, R_5$ may be connected in series and/or parallel, so we need to simplify the circuit.

2. Find the total resistance: Calculate the equivalent resistance $R_{\text{eq}}$ of the circuit using series and parallel rules.

   • Series connection: For resistors in series, the total resistance is the sum of individual resistances: $R_{\text{total}} = R_1 + R_2 + R_3 + \dots$

   • Parallel connection: For resistors in parallel, the total resistance is found by: $\frac{1}{R_{\text{total}}} = \frac{1}{R_1} + \frac{1}{R_2} + \dots$

3. Use Ohm’s Law: Once the total resistance is found, use Ohm's Law to calculate the total current $I_{\text{total}}$: $I_{\text{total}} = \frac{V}{R_{\text{eq}}}$ where $V$ is the voltage of the battery.

4. Current through $R_5$: Once we find the current in the circuit, the current through each resistor can be determined based on the configuration of the resistors (whether in series or parallel).
