Electricity Review

Front

What is electricity?

Back

Electricity is the flow of electric charge, typically carried by electrons, which can be used to power devices and perform work.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, so the same current flows through all components. In a parallel circuit, components are connected across common points, allowing multiple paths for current.

Front

What is resistance?

Back

Resistance is a measure of the opposition to the flow of electric current, measured in ohms (Ω).

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): V = I × R.

Front

What is an insulator?

Back

An insulator is a material that does not allow electric current to flow easily, such as rubber or glass.

Front

What is a conductor?

Back

A conductor is a material that allows electric current to flow easily, such as copper or aluminum.

Front

What happens when two like charges are brought near each other?

Back

Like charges repel each other, meaning they push away from one another.

Front

What happens when two opposite charges are brought near each other?

Back

Opposite charges attract each other, meaning they pull towards one another.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, which can result in sparks or shocks when discharged.
