Conducter

Helps flow of electrons

Insulator

Stops flow of electrons

Resister

Slows flow of electrons

Voltage

Electric pressure/ force that pushes electrons through a circut

Current

The flow of electric charge in a circuit, typically measured in amperes.

resistance

A measure of the opposition to the flow of electric current in a circuit, usually expressed in ohms.

electrical power.

At which electricity generated, transferred, or consumed.

conventional current

The flow of electric charge assumed to move from positive to negative terminals, contrary to the actual flow of electrons.

electron flow

The actual movement of electrons in a circuit, from negative to positive terminals, opposite to conventional current.

parallel circuit

A type of electrical circuit where two or more paths exist for current to flow.

series circuit

Only one path for electrons to flow

Closed circuit

An electrical circuit that is complete and allows current to flow through without interruption.

open circuit

An electrical circuit that is incomplete, preventing current from flowing due to a break or gap.

AC

An alternating current (AC) is an electric current that periodically reverses direction, typically used in power supplies.

DC

Direct current (DC) is an electric current that flows in a single direction, commonly used in batteries and electronic devices.

Load

any component in a circuit that consumes electricity to perform work, such as lighting, heating, or motion.

Fuse

A safety device that interrupts excessive current flow in an electrical circuit, protecting the wiring and devices from damage. Must be replaced after use

Circuit breaker

A switch that automatically stops the flow of electricity in a circuit when it detects an overload or fault, providing protection for electrical systems and devices. Reusable

Volts

Measures voltage, symbol is E or V

Amps/ amperes

Measures electric current, symbol is A could be I sometimes tho

Ohms

Measures electrical resistance, symbol is Ω

Watts

Measures electrical power, symbol is W. This is calculated by multiplying voltage by current.

Voltmeter

A device used to measure electric potential difference in volts, symbol is V.

Electric potential difference is

Voltage

Ammeter

A device used to measure electric current in amperes, symbol is A.

The higher the number of Amps the

Greater the number of volts

Ohms law

V= I time R or voltage equals current times resistance
