On which limb is the RA electrode placed?

Explanation:
RA stands for Right Arm, so the electrode is placed on the right arm. In a standard ECG, limb electrodes are placed on the arms and legs to form the limb leads, with the right arm electrode designated as RA, the left arm as LA, and the left leg as LL. The right leg electrode (RL) is usually used as the ground to reduce noise. This arrangement is what makes the RA position specifically the right arm.
