Electric Circuits, Effects of Current, and Components

Vocabulary practice flashcards covering fundamental concepts in electric circuits, series and parallel arrangements, circuit protection, output devices, and the magnetic and chemical effects of electricity.

Series circuit

An electrical circuit in which components are connected one after another in succession, providing only a single pathway along which electric current can flow.

Parallel circuit

An electrical circuit in which components are connected side-by-side, providing multiple separate paths for the electric current to divide and flow through.

Electrical resistance

The opposition that a conductor or material offers against the flow of an electrical current.

Short circuit

A condition where current bypasses the main electrical load by traveling through an unintended path of least resistance, causing circuit resistance to drop and current to surge dangerously.

Fuse

A protective safety device containing a low-melting-point conductor that melts to break the circuit when current becomes excessive, preventing overheating and fires.

Electromagnet

A temporary magnet formed by winding coils of insulated wire around a metal core, which produces a magnetic field only while an electric current passes through the wire.

Electrolysis

The chemical process of decomposing a compound into its constituent elements using energy supplied by an electric current.

Anode

The positive electrode in an electrolytic cell, connected to the positive terminal of the power supply or battery.

Cathode

The negative electrode in an electrolytic cell, connected to the negative terminal of the power supply or battery, where metals typically deposit during electrolysis.

Light emitting diode (LED)

A miniature output device that converts electrical energy into light energy without becoming hot, using less power and lasting longer than traditional incandescent bulbs.
