It seems like you're referring to a specific circuit with an ammeter labeled A2 reading 1 (likely 1 ampere), but I don't see the figure or additional details about the circuit. To help you effectively, could you please provide:

• The circuit diagram or a description of the circuit (components, connections)
• What exactly you want to find out (e.g., current in another branch, voltage, resistance, etc.)
• Any given values or parameters in the circuit

Once I have this information, I can analyze the circuit and provide a detailed answer.
