The switch’s electrical energy transforms to sound energy, which the wire transfers to the bell.
The switch’s electrical energy transforms to sound energy, which the wire transfers to the bell.
The battery’s chemical energy transforms to sound energy, which the wire transfers to the bell.
The battery’s chemical energy transforms to sound energy, which the wire transfers to the bell.
The battery’s chemical energy transforms to electrical energy, which the bell then transforms to sound energy.
The battery’s chemical energy transforms to electrical energy, which the bell then transforms to sound energy.
The switch transforms electrical energy to chemical energy, which the bell then transforms to sound energy.
The battery’s chemical energy transforms to electrical energy, which the bell then transforms to sound energy.
The correct answer is:
- The battery's chemical energy transforms to electrical energy, which the bell then transforms to sound energy.
The correct answer is:
The battery's chemical energy transforms to electrical energy, which the bell then transforms to sound energy.
To understand this, let's break down the energy transformations step by step:
1. The battery in the circuit stores chemical energy. This chemical energy can be converted into electrical energy when the circuit is closed (switch turned on).
2. When the switch is turned on, it allows the flow of electrons from the battery through the wire. This movement of electrons constitutes an electrical current, carrying electrical energy.
3. The wire acts as a conductor, transferring this electrical energy from the battery to the bell.
4. The bell is designed to convert electrical energy into sound energy. It does so by using the electrical current to vibrate a metal diaphragm, producing sound waves.
Therefore, from start to finish, the energy transformations that occur are:
Battery's chemical energy transforms into electrical energy -> Electrical energy travels through the wire -> Bell transforms electrical energy into sound energy.
Other options mentioned are incorrect:
- The switch does not convert electrical energy to chemical energy. Its purpose is to open or close the circuit, allowing or blocking the flow of current.
- The wire does not transfer energy from the switch to the bell. The wire acts as a conduit for the flow of electrical energy between the battery and the bell.
