How Electricity Works /without Video

What are the three particles that make up an atom?

• Neutrons, Protons, Electrons

• Atoms, Neutrons, Electrons

• Protons, Atoms, Molecules

• Protons, Electrons, Molecules

Where are the electrons located in an atom?

• Inside the nucleus

• In the valence shell

• Outside the nucleus in orbital layers

• Bound to the protons

What is the charge of a neutron?

• No charge

• Negative

• Positive

• Varies with the atom

What materials are known as conductors?

• Insulators such as glass and rubber

• Materials with strongly bound electrons

• Materials that do not allow the flow of electrons

• Most metals

What is the function of a capacitor in a circuit?

• To increase the flow of electrons

• To store and release electrons

• To convert from AC to DC

• To generate electricity

What does a volt measure?

• The number of electrons in a coulomb

• The flow of electrons

• The driving force of electrons within a circuit

• The resistance in a circuit

What is the unit used to measure the flow of electrons?

• Coulomb

• Volt

• Ampere

• Joule

What happens when a wire is wrapped into a coil and current passes through it?

• Converts from AC to DC

• Reduces the flow of electrons

• Generates a magnetic field

• Becomes an insulator

What is the main difference between AC and DC current?

• AC flows in one direction, while DC flows in two

• DC is only used in solar panels

• AC can only be used in batteries

• DC flows in one direction, while AC reverses direction

What is the purpose of a transformer?

• To generate magnetic fields

• To convert electrons into protons

• To increase or decrease voltage

• To store electrons
