Point J on the ladder diagram should be connected at terminal ___ on the relay socket.

In relay logic diagrams, specific points on the ladder represent connections to different terminals on the relay socket, which control the operation of the relay. Terminal "1" is typically connected to the control source, making it essential in establishing the power flow to energize the relay when certain conditions are met.

Connecting Point J to terminal "1" means that it will directly influence the relay's operation, allowing the correct circuit to be activated when the appropriate control signal is received. This illustrates how the control logic is implemented in a ladder diagram, ensuring that the relay responds as designed in the control circuit.

The other terminals, while they may serve specific functions in different contexts, do not serve the same purpose as terminal "1" in this scenario. Therefore, it's crucial to understand the significance of connecting to terminal "1" when specifying the connection point for proper relay operation in the ladder logic setting.
