Introduction
In this lesson we are going to work about electricity and what are the effects of electric current.
Besides, we will learn to use the electricity.
Task
1.- Match the effects of electric current to the device.
a) a mixer
b) a vacuum cleaner
c) a bulb
d) an iron
e) a sandwich maker
f) an electric heater
g) a hairdryer
2.- See the video and answer the question. What is the main characteristic of the Joule's Effect?
3.- Complete the sentence below using these words: LONG, HEAT, SMALL, ROLLED
The conductor wire is ________________ up inside devices like a toaster or a hairdryer because then a __________ piece of wire can fit in a ____________ space and produce more______________
4.- True or false? If the sentece is false, correct it.
a) The components used to produce heat are called motors.
b) The energy transported by an electric current has different effects on the components that the current flows though.
c) Incandescent and halogen bulbs have some gases that emit light when they recieve an electric charge.
d) Motors are based on the Joule's effect between a magnet and a conductor wire placed in one or more loops inside it.
e) If the shaft of the motion rotates sufficiently fast it becomes a generator.
5.- Match the type of the bulb with its characteristics.
| contain gas which reacts with electricity | |
| get hot | Halogen bulbs and fluorescent tubes |
| last a long time | Low-energy bulbs and fluorescent tubes |
| are less effiecient |
