Analog devices connected using a voltage type analog signal are connected in what?

• A. Series
• B. Parallel
• C. Daisy Chain
• D. Ring

Answer: (B)

Voltage-type analog signals convey a specific potential difference that each device needs to sense directly. To share this signal among multiple devices, you connect them across the same two conductors, i.e., in parallel. This arrangement keeps the voltage constant at each device so every input reads the same signal regardless of how many devices are connected. If you put devices in series, the voltages would split according to each device’s load, so the readings would vary and the signal integrity would be lost. Ring or daisy-chain topologies aren’t used for simple voltage distribution because they add unnecessary complexity and loading effects. In short, parallel wiring lets every device see the same voltage signal reliably.
