Electricidad: electricidad estática

The video explains static electricity, where charges develop in objects but do not transfer. It illustrates how static electricity causes clothes to stick in a dryer due to electron transfer between fabrics. The video also describes how walking on a carpet can lead to an electric shock when touching a metal object, as electrons jump from your body to the object, resulting in an electric discharge.

What causes clothes to stick together in a dryer?

• The weight of the clothes

• The heat from the dryer

• The transfer of electrons between fabrics

• The speed of the dryer

What happens when you walk on a carpet and then touch a metal object?

• You experience a small electric shock

• You hear a loud noise

• You see a spark

• You feel a cold sensation

What is the process called when electrons jump from your fingers to a metal object?

• Optical reflection

• Thermal conduction

• Magnetic attraction

• Electric shock

What is an electric discharge?

• A gradual movement of charges

• A sudden movement of charges

• A slow build-up of charges

• A constant flow of charges

Why do you sometimes feel a shock in dry weather?

• Because of increased humidity

• Due to the presence of static electricity

• Because of the high temperature

• Due to the lack of moisture in the air
