Understanding Flashlight Circuits

The video explains how flashlights work by using electricity from batteries to light a bulb. It introduces the concept of circuits, which are paths that electricity follows. The video demonstrates building a simple circuit and explains how switches can control the flow of electricity. It also highlights the presence of circuits in everyday devices like cars and computers. The video concludes with a thank you to viewers.

What is the main source of power in a flashlight?

• Wind energy

• Batteries

• Hydraulic power

• Solar panels

What is the path called that electricity follows to light up a bulb?

• Line

• Track

• Circuit

• Route

In a simple circuit, what is often used to create the path for electricity?

• Rubber bands

• Wooden sticks

• Wires

• Plastic tubes

What happens when there is a gap in the circuit?

• The electricity flows faster

• The circuit becomes stronger

• The electricity stops

• The bulb lights up

What device is used to open or close a circuit?

• A capacitor

• A resistor

• A switch

• A transformer

What happens when you press the button in a circuit with a switch?

• The bulb gets brighter

• The circuit breaks

• The circuit becomes complete

• The electricity reverses

What is the role of a switch in a circuit?

• To increase voltage

• To create a gap

• To change the bulb

• To add more power

What does the button in the circuit demonstration represent?
