Electricity and inventions. In this video we will learn about two types of electric
00:00:00
currents and we will learn about electrical safety. Types of electric current. Using
00:00:10
electrical energy. Some technologies that use electrical energy were invented at the end of
00:00:23
the 19th century. We have the direct current and the alternating current.
00:00:31
Thomas Alva Edison invented the direct current. The current moves in the same
00:00:39
direction through power lines. Nikola Tesla invented the alternating current.
00:00:47
the direction of the current changes periodically. Electrical safety.
00:00:56
Electricity can be very dangerous, so we need to use it carefully. Here are some
00:01:10
things that you should not do. Do not use electrical appliances in the bath or
00:01:20
shower. Do not plug in an appliance with wet hands. So you have to be careful when
00:01:29
you have water near a plug or an electrical appliance. Do not open or
00:01:38
repair a plugged appliance. You have to unplug the appliance before you try to
00:01:47
to open or repair it. Do not clean a plugged appliance with a damp cloth. All right, so make
00:01:56
sure that you are very careful with appliances, with electrical appliances. Okay, until next time, goodbye!
