Transcribed Image Text:If \( \xi_1 = 12 \, \text{V}, \, I_2 = 1 \, \text{A}, \, R_2 = 1 \, \Omega, \, I_3 = 2 \, \text{A}, \) and \( R_3 = 3 \, \Omega, \) find the power dissipated by resistor \( R_1. \)
Transcribed Image Text:This diagram depicts a basic electrical circuit with two power sources and three resistors. It is organized in a parallel configuration with the following elements:
- **Power Sources**:
- \( \xi_1 \) and \( \xi_2 \). These represent the electromotive forces (emf).
- **Resistors**:
- \( R_1 \), \( R_2 \), and \( R_3 \).
- **Current Directions**:
- \( I_1 \) flows through \( R_1 \).
- \( I_2 \) flows through \( R_2 \).
- \( I_3 \) flows through \( R_3 \).
**Description:**
- The circuit is split into two branches with separate power sources, indicating that each branch is powered independently.
- The current flows from the positive terminal of the power sources towards the negative, through the resistors, as indicated by the arrows next to each current label.
This diagram is useful for understanding basic principles of parallel circuits and analyzing how current flows through multiple pathways when different resistors and power sources are involved.
