Chapter 12 The Boy Who Harnessed the Wind

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where components are connected in a single path, so the same current flows through all components.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where components are connected across common points or junctions, allowing multiple paths for current to flow.

Front

What is the main idea of Chapter 12 in 'The Boy Who Harnessed the Wind'?

Back

The main idea is that William discovers new uses for the windmill, such as charging phones.

Front

What is a circuit breaker?

Back

A circuit breaker is a safety device that automatically shuts down the electrical circuit if it detects an overload or fault.

What is the purpose of a windmill?

Back

The purpose of a windmill is to convert wind energy into mechanical energy, which can then be used for various applications like generating electricity or pumping water.

Front

What is AC current?

Back

AC (Alternating Current) is an electric current that reverses direction periodically, commonly used in household power supply.

Front

What is DC current?

Back

DC (Direct Current) is an electric current that flows in one direction only, commonly used in batteries.

Front

Why is it important to have a generator in a wind energy system?

Back

A generator is important in a wind energy system to convert mechanical energy from the windmill into electrical energy.
