Understanding Circuits

The video tutorial explains the difference between closed and open circuits. A closed circuit is an unbroken path where electricity can flow, lighting up a bulb. In contrast, an open circuit occurs when the path is broken, preventing electricity from flowing and the bulb from lighting up.

What is a closed circuit?

• A circuit with no wires

• A circuit where both wires are connected to the terminals

• A circuit that does not allow electricity to flow

• A circuit with a broken path

What happens when one wire is disconnected in a circuit?

• Electricity flows continuously

• The path becomes broken

• The bulb lights up

• The circuit remains closed

Why doesn't the bulb light up when the path is broken?

• Because the wires are too long

• Because the bulb is faulty

• Because electricity cannot flow through a broken path

• Because the circuit is closed

What is an open circuit?

• A circuit with a complete path

• A circuit with a broken path

• A circuit with extra wires

• A circuit that lights up a bulb

In an open circuit, what is the state of electricity flow?

• Electricity flows freely

• Electricity cannot flow

• Electricity is stored

• Electricity flows intermittently
