Electricidad estática

The video explains the difference between static electricity and electric current. Static electricity involves charges that do not flow, unlike electric current where charges move through a medium like a wire. It also describes how static charges can be easily generated in insulating materials, such as by rubbing a balloon with skin or fabric.

What is the main difference between static charges and electric current?

• Static charges do not move through a medium, while electric current does.

• Static charges occur in conductors, while electric current occurs in insulators.

• Static charges are always positive, while electric current is always negative.

• Static charges involve moving charges, while electric current does not.

In which type of materials is it easiest to generate static charges?

• Conducting materials

• Insulating materials

• Metallic materials

• Magnetic materials

Which of the following is an example of generating static charges?

• Rubbing a balloon on a piece of fabric

• Connecting a wire to a power source

• Turning on a switch to light a lamp

• Using a battery to power a light bulb

What happens when a balloon is rubbed with a piece of skin or fabric?

• The balloon loses its insulating properties.

• The balloon becomes a conductor.

• The balloon becomes magnetic.

• The balloon generates static charges.

Which of the following statements is true about static charges?

• Static charges can only be generated in metals.

• Static charges are a type of electric current.

• Static charges require a medium to flow.

• Static charges can be generated by friction.
