Question
**Educational Website Transcription** --- **Question:** What is the current through resistor \( R_1 \) in the circuit shown? **Circuit Explanation:** The image depicts an electrical circuit with three resistors and two voltage sources: - **Resistors:** - \( R_1 \): 30 Ω - \( R_2 \): 60 Ω - \( R_3 \): 90 Ω - **Voltage Sources:** - 10 V is across \( R_1 \). - 20 V is across \( R_2 \). **Circuit Configuration:** The resistors are arranged in a parallel combination. Each voltage source is applied across its respective resistor, suggesting multiple potential branches through which current can flow. **Problem Objective:** Determine the current flowing through resistor \( R_1 \). **Key Concept:** - Use Ohm's Law: \( I = \frac{V}{R} \) to calculate the current through each resistor based on the voltage across it. This exercise illustrates principles of current distribution in parallel circuits.
