Electricity and Magnetism

Front

Positively charged particles in an atom

Back

Protons are positively charged particles found in the nucleus of an atom.

Front

Electric charges always flow from _____ areas to _____ areas.

Back

Electric charges always flow from negative areas to positive areas.

Front

What produced the electricity in the electromagnets we made in class?

Back

The electricity in the electromagnets was produced by a battery.

Front

Metal is a good conductor

Back

True. Metals allow electric charges to flow through them easily.

Front

To build a basic circuit, you need wires, a light bulb, and _____

Back

A battery is needed to provide the electrical energy for the circuit.

Front

What is an insulator?

Back

An insulator is a material that does not allow electric charges to flow through it easily.

Front

What is the unit of electric current?

Back

The unit of electric current is the Ampere (A).

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). It can be expressed as V = I × R.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electric current to flow from a power source to a load and back.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, which can cause them to attract or repel each other.
