Question

In a simple series circuit, why does the bulb light when you close the switch?
a) Because the switch produces electricity
b) Because closing the switch completes the circuit
c) Because closing the switch breaks the circuit

Answer 1

Answer:

b) Because closing the switch completes the circuit

Answer 2

In a simple series circuit, the bulb light when you close the switch because closing the switch completes the circuit. (Option b)

• The function of the switch in a circuit is to make (close/on) or break (open/off) the circuit.
• Only when the switch is closed, the current will begin to flow through the circuit.
• The switch does not produce any electricity, it only makes a path for the electricity to flow.
• Closing the switch does not break, but it makes the circuit or it completes the circuit and makes it ready for current flow.
• A switch makes it easy to on and off the simple series circuit whenever required or else the electrical wires will have to be disconnected each time.
