Untitled Flashcards Set

What are the three parts of an atom?

Protons, Neutrons, and Electrons.

What charge do protons carry?

Positive charge.

What charge do electrons carry?

Negative charge.

What is an electrically neutral atom?

An atom with equal numbers of protons and electrons.

What is static charge?

An unbalanced negative or positive charge on an object.

How can an object become positively charged?

By giving away electrons.

What happens to an object when it receives electrons?

It becomes negatively charged.

What does Coulomb's Law state about electric charges?

More charge present results in a stronger electric force; greater distance results in a weaker force.

What materials are considered good conductors of electricity?

Metals and water.

What are good insulators of electricity?

Rubber, plastic, wood, and glass.

What is conduction in terms of electric charge?

The transfer of electric charge by simple touch.

What is induction?

The transfer of electric charge by scrambling electrons without direct contact.

Define friction as it relates to electrical charge.

Charge created by rubbing, transferring electrons from one object to another.

What does it mean for an object to be polarized?

Electrons concentrate at one end of the object.

What is electric discharge?

When unbalanced charges become balanced, such as when shocking yourself on a doorknob.

What is electric current?

The movement of electrically charged particles, typically electrons.

What is a closed circuit?

A complete path through which electric current can flow.

What is a battery?

A storehouse of electrical energy that converts chemical energy into electrical energy.

What is Ohm's Law?

It describes the relationship between current, voltage, and resistance in a circuit.

What happens in a series circuit?

There is only one path for current to flow, leading to higher resistance and lower current.

What characterizes a parallel circuit?

There are multiple paths for current to flow, resulting in lower resistance and higher current.

What is a short circuit?

A complete circuit with no resistance; very dangerous due to potential overheating.

What can cause electric shock?

When electric current flows through your body, often by touching a live wire or appliance.

What is resistance?

A measure of how difficult it is for electrons to flow through a material.

How is current measured in the metric system?

In Amperes (A).

What is voltage?

The amount of energy the source uses to move electrons through an electric circuit.

What are Fuse Boxes and Circuit Breakers used for?

To automatically open a circuit if the current becomes too high, preventing fires.
