Electricity Quiz

What are the three particles that make up an atom?

• Neutrons, protons, and electrons

• Neutrons, positrons, and electrons

• Neutrons, protons, and photons

• Neutrons, positrons, and photons

Answer explanation

An atom is made up of neutrons, protons, and electrons. These three particles are responsible for the structure and properties of an atom.

Which particle is found inside the nucleus of an atom?

• Photons

• Electrons

• Protons

• Neutrons

Answer explanation

Protons are the particles found inside the nucleus of an atom. They have a positive charge and determine the element's identity.

What is the outer-most shell of an atom called?

• Valence shell

• Nucleus shell

• Orbital shell

• Electron shell

Answer explanation

The outer-most shell of an atom is called the valence shell. It is responsible for the chemical properties of the atom and determines how it will interact with other atoms.

What are materials called that can pass electrons?

• Conductors

• Insulators

• Neutrons

• Protons

Answer explanation

Conductors are materials that can pass electrons.

What is the unit of measurement for voltage?

• Volt

• Joule

• Coulomb

• Amp

Answer explanation

The unit of measurement for voltage is Volt. Volt is the correct choice because it represents the electric potential difference between two points in a circuit.

What is the flow of electrons called?

• Magnetic field

• Voltage

• Resistance

• Current

Answer explanation

The flow of electrons is called current. It represents the movement of electric charge through a conductor.

What is resistance in a circuit?

• The voltage in the circuit

• The flow of electrons

• The restriction to the flow of electrons

• The magnetic field generated by the circuit

Answer explanation

Resistance in a circuit is the restriction to the flow of electrons.

What type of current flows back and forth in a circuit?

• Positive current

• Alternating current

• Negative current

• Direct current

Answer explanation

Alternating current is the type of current that flows back and forth in a circuit. It is different from direct current, which flows in only one direction.

What can be used to convert AC to DC?

• Capacitors

• Power electronics

• Transformers

• Resistors

Answer explanation

Power electronics can be used to convert AC to DC. They are specifically designed for this purpose and are capable of efficiently converting the alternating current to direct current.

What is the purpose of a capacitor in a circuit?

• To store and release electrons

• To generate a magnetic field

• To convert AC to DC

• To restrict the flow of electrons

Answer explanation

A capacitor in a circuit is used to store and release electrons.
