Choice B.

Work Step by Step

Each new device is added to the circuit in parallel to the others, such as when multiple appliances are plugged into a power strip. The voltage across every device stays the same as more devices are added. However, each new device creates a path for more current to flow, causing the total current demanded to increase. When the current becomes too high, the circuit breaker trips/opens, cutting off the power as a safety measure.
