Video transcript on Current Electricity -

Hi! today we'll learn about electrical current. There are two main types of electricity static electricity and the current electricity. Static electricity is produced by rubbing together two or more objects and making friction. That’s funny!

What is Electrical Current

Electrical current is the flow of electric charge across an electrical field. Now let’s learn about electrical current in detail!

What is Current

Current is the rate of flow of electrons. It’s produced by moving electrons and it’s measured in amperes. Unlike static electricity, electricity electrical current must flow through a conductor. Usually copper wire current with electricity is similar to the current when you think of a river. The river flows from one spot to another and the speed it moves is the speed of the current. With electricity current, it’s a mass of the amount of energy transferred over a period of time.

Current with Electricity

That energy is called a flow of electrons. One of the results of current is the heating of the conductor when an electric stove heats up it’s because of the flow of current.

Sources of Electricity

There are different sources of electrical current including the chemical reactions taking place in a battery. The most common source is the generator. A simple generator produces electricity when a coil of copper turns inside a magnetic field. In a power plant, electromagnets spinning inside many coils of copper wire generate vast quantities of electrical current. There are two main kinds of electric current. Direct - DC, and alternating- AC. Don’t get confused by the two. Direct current is like the energy that you get from a battery. Direct current is used as a primary energy source in various industries. It’s most likely used in low voltage applications such as aircraft applications changing batteries etc.

Alternating Current

Alternating current is like the plugs in your wall. Alternating current is used to operate appliances for both household and industrial and commercial use. The big difference between the two is that DC is a flow of energy and AC can turn on and off. AC reverses the direction of the electrons.

Now answer the 5 questions associated with the video:

Answer the questions about current electricity:

1. There is only ONE type of electricity. True or false?

2. Current electricity is the flow of electric charge across an electric field? True or false?

3. Current Electricity flows throw a/an
A. Insulator
B. conductor

4. Direct current is a flow of energy. True or false?

5. The energy found in current electricity is due to the flow of

Final answer:

Electricity has both static and current forms, with current electricity being the flow of electric charge across an electric field through conductors. Direct current is a continuous flow of energy in one direction, and the energy in current electricity comes from the flow of electrons.

Step-by-step explanation:

You have some good questions about current electricity! Here are the answers:

  1. There is only ONE type of electricity. False. There are at least two main types: static electricity and current electricity.
  2. Current electricity is the flow of electric charge across an electric field? True.
  3. Current Electricity flows through a/an B. conductor.
  4. Direct current is a flow of energy. True. Direct current (DC) flows continuously in one direction through a conductor.
  5. The energy found in current electricity is due to the flow of A. Electrons.
