Question
**Educational Problem Statement:** **Determine the magnitudes and directions of the currents in each resistor shown in the figure.** The batteries have electromotive forces (emfs) of \( \mathcal{E}_1 = 9.2 \, \text{V} \) and \( \mathcal{E}_2 = 11.8 \, \text{V} \). The resistors have values of \( R_1 = 32 \, \Omega \), \( R_2 = 30 \, \Omega \), and \( R_3 = 33 \, \Omega \). [Refer to Figure 1 for the circuit diagram.] **Part A** - **Instructions**: Ignore the internal resistance of the batteries. - **Task**: Express your answers using two significant figures. Enter your answers numerically separated by commas. - **Response Area**: \( I_1, I_2, I_3 = \_\_\_ \) **Note**: The figure referenced, labeled as Figure 1, is assumed to provide a circuit where these components are connected in a specific configuration. The task is to calculate the current flowing through each resistor based on the provided values of voltage and resistance using techniques such as Kirchhoff’s laws.

This diagram represents an electrical circuit consisting of two voltage sources and three resistors. The components are arranged as follows: 1. **Voltage Sources**: - \( \mathcal{E}_1 \) and \( \mathcal{E}_2 \) are two independent voltage sources. \( \mathcal{E}_1 \) is connected in series with resistor \( R_1 \), and \( \mathcal{E}_2 \) is connected in parallel. 2. **Resistors**: - \( R_1 \) is in series with \( \mathcal{E}_1 \). - \( R_2 \) is placed in parallel between the two branches containing \( \mathcal{E}_1 \) and \( \mathcal{E}_2 \). - \( R_3 \) is connected in series with \( R_2 \), completing the circuit. The circuit can be analyzed using Kirchhoff's laws to determine the current and voltage across each resistor. This setup is common for studying series and parallel resistor combinations and their impact on the overall circuit behavior.
