Electricity

A conductor is a material that allows the flow of electric current. Examples include metals like copper and gold.

Gold ring is a common conductor of electricity.

Protons have a positive charge.

A circuit is a closed path through which electric current flows.

Static electricity is the buildup of electric charge on the surface of objects, often resulting in a spark or discharge.

Current electricity is the flow of electric charge through a conductor, typically measured in amperes.

Thicker wires have less resistance than thinner wires.

Voltage is the electric potential difference between two points in a circuit, measured in volts.

An insulator is a material that does not allow electric current to flow through it easily. Examples include rubber and glass.

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 is expressed as V = I × R.
