Final answer:
The cathode in line notation of a battery is typically represented by the right side.
Step-by-step explanation:
The cathode in line notation of a battery is typically represented by the right side. In line notation, the anode is always placed on the left side, and the cathode is placed on the right side. This convention follows the left-to-right direction in which the schematic is read, starting with the anode and ending with the cathode.
