Electricidad y Ley de Ohm

What is the definition of electricity?

• Electricity is a form of energy that allows neutral particles to move within an atom.

• Electricity is a form of energy that allows negatively charged particles to move from one atom to another.

• Electricity is a form of energy that allows positively charged particles to move from one atom to another.

• Electricity is a form of energy that allows neutral particles to move from one atom to another.

What is electric charge?

• Electric charge is the imbalance between electrons and protons in matter.

• Electric charge is the balance between electrons and protons in matter.

• Electric charge is the absence of protons in matter.

• Electric charge is the absence of electrons in matter.

What's the difference between electric current and alternating current?

• There's no difference between electric current and alternating current.

• Electric current flows in one direction, while alternating current changes direction several times per second.

• Electric current and alternating current are the same thing.

• Electric current changes direction several times per second, while alternating current flows in one direction.

What is an electric circuit?

• An electric circuit is a network with an open path through which electric current flows.

• An electric circuit is a network with a closed path through which electric current flows.

• An electric circuit is a network with a closed path through which electric current does not flow.

• An electric circuit is a network with an open path through which electric current does not flow.

What is the purpose of a one-way switch?

• It increases the speed of the electric current.

• It allows or cuts off the flow of electric current.

• It completely stops the electric current.

• It regulates the amount of electric current flowing.
