Question

Once the reserve ___inside the cells is over, ___ and the circuit breaks.

• A. of excess electron, the delivery of energy starts
• B. of excess electron, the delivery of energy stops
• C. of excess protons, the delivery of energy stops
• D. of excess protons, the delivery of energy starts

Answer 1

The correct option is B

of excess electron, the delivery of energy stops

The delivery of energy/current stops and the circuit breaks as soon as the reserve of excess electron inside the cells is over. Thus, the device connected to the circuit, such as a bulb, dc motor stops working.
