🗑
|
||||
| The inventor of the first electric light bulb was... (at least he got the credit!) | Thomas Edison
🗑
|
||||
| Poles are found at the _____ of a magnet. | ends (extremo)
🗑
|
||||
| An example of a good insulator is... | rubber, plastic

| Rubbing a balloon with a cloth gives it a negative charge. It sticks to the wall because the wall provides a... | positive charge
🗑
|
||||
| The person who discovered that by moving a magnet near a wire electricity could be made; also invented the first transformer | Michael Faraday
🗑
|
||||

🗑
|
||||
| Materials that are generally good conductors | Metal
🗑
|
||||
| Changing energy from one form to another - example, a battery changes chemical energy into electrical energy - example a car changes chemical energy in gasoline to movement of a car - some energy is wasted in the process | Transformation of energy
