**Transcription for Educational Website** **Question:** Let \( V_s = 20 \, V \) in the circuit of Fig. 3.5. What is the current through \( R_3 \)? **Circuit Diagram Explanation (Fig. 3.5):** - The circuit contains a voltage source \( V_s = 20 \, V \) on the left. - \( R_1 \) is a resistor with a resistance of \( 1.0 \, k\Omega \) connected in series with the voltage source. - Following \( R_1 \), the circuit splits into two parallel branches: - One branch contains \( R_2 \) with a resistance of \( 2 \, k\Omega \). - The other branch contains \( R_3 \) with a resistance of \( 2 \, k\Omega \). **Current Notation:** - \( I_T \) denotes the total current flowing through the circuit. **Answer Choices:** - \( \circ \) 5 mA - \( \circ \) 10 mA - \( \circ \) 20 mA - \( \circ \) 15 mA **Note:** To solve for the current through \( R_3 \), use the rules for series and parallel circuits to determine how the current divides across the parallel resistors \( R_2 \) and \( R_3 \).
