Energy

Electric Circuit

A pathway travelled by electrical energy.

Electrons

Negatively charged particles that carry electrical energy in a circuit.

Power Source

The component that provides energy to the circuit, such as a battery.

Load

A component of the circuit that uses energy, like a resistor.

Series Circuit

A circuit in which components are connected in a single pathway.

Parallel Circuit

A circuit that provides multiple pathways for electrons to travel.

Ammeter

A device that measures the current through the circuit.

Voltmeter

A device that measures the voltage supplied to the components.

Transistor

A semiconductor device that acts as a switch or amplifier in a circuit.

Integrated Circuit

A microelectronic device that contains numerous components in a single chip.

Resistance

The opposition to the flow of electric current.

Ohm's Law

States that the current through a conductor between two points is directly proportional to the voltage across the two points.

Fuse

A safety device that interrupts the flow of current when it exceeds a specific level.

Circuit Breaker

A device that automatically stops the flow of current to prevent overheating and damage.

Electrical Energy

Energy carried by moving electrons in a circuit.

Capacitance

The ability of a system to store
