**Diagram Explanation:**
The figure illustrates a circuit diagram associated with electrocardiograph connections. It includes:
- A **Recorder** connected to an **Amplifier**.
- Two branches with a **Resistor (R)** and a **Capacitor (C)** in series, representing the connections to the left-leg and right-leg electrodes.
- The right-leg electrode is also labeled as "ground."
- Another connection is directed towards the "arm electrode."
This configuration demonstrates the coupling of electrodes using resistors and capacitors to register electrical signals from the heart accurately.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F592c3157-16ae-4adf-9e37-2db2ec2ebc8f%2Faccb8f39-2ed4-418c-9647-6d949ac1f7f2%2Ffwc3syl_processed.png&w=3840&q=75)
