Question

What is the current Ia

This diagram represents a simple electrical circuit. **Components:** 1. **Voltage Source:** - A 9V battery is depicted on the left side of the circuit. 2. **Resistors:** - Two resistors are included in the circuit: - \( R_1 = 3 \, \Omega \) is connected in series to the battery. - \( R_2 = 9 \, \Omega \) is connected in series with \( R_1 \). 3. **Current Designation:** - The current flowing through the circuit is indicated by \( I_a \), with an arrow showing the conventional direction from the positive terminal of the battery through \( R_1 \) and \( R_2 \). **Explanation:** - The circuit is a series circuit with a voltage source and two resistors. The total resistance in the circuit can be calculated by summing \( R_1 \) and \( R_2 \), giving a total of \( 12 \, \Omega \). - The current \( I_a \) can be determined using Ohm's Law: \( I = \frac{V}{R} \), where \( V \) is the voltage (9V) and \( R \) is the total resistance (12Ω).
