Terms in this set (34)

High resistance

Can be caused by:
1. corroded connections or sockets
2. loose terminals in a conductor
3. loose ground connections

A term used to describe the device and electrical current is flowing through (example: light bulb)

It requires 1 volt to push 1 ampere through 1 ohm of resistance

Any circuit that is not complete or lacks continuity, such as a broken wire

From the current to flow through from the power source to the resistance

(In electrical terms) Such as a battery or generator (alternator)

Protection device

From harmful overloads (excessive current flow, fuses, circuit breakers, fusible links)

Return path (ground leg)

Electrical current from the load back to the power source so that there is a complete circuit

A portion of the circuit is bypassed

Short to voltage

When the power side of one circuit is electronically connected to the power side of another circuit

Is the path that electrons travel from one power source, through a resistance and back to the power source

Complete circuit

A type of electrical circuit that has continuity; current would flow if connected to power and ground

A circuit that is continuous throughout is said to have continuity

Electrical load (or resistance)

Converts electrical energy into heat, light, and motion

Short to ground

A type of short circuit that occurs when the current bypasses part of the normal circuit and flows directly to ground

Have a positive charge

Neutral (no charge)

Have a negative charge

The smallest particle that an element can be broken into and still retain the properties of that element.

The movement of electrons from one atom to another.

The same number of Electrons and protons (balanced)

When an atom is not balanced, it becomes a charged particle called ---

Process is defined as the flow of electricity

Materials allow the flow of electrons

Materials that do not allow the flow of electrons

Materials that can act as conductors or insulators

Conventional Theory

Theory of the flow of electricity through a conductor from positive to negative

Electron Theory

States that there is electron flow from negative to positive

The unit used throughout the world to measure current flow

Unit of measurement for electrical pressure

Electrical Potential

If there is voltage present in a conductor, there is potential for current flow

How volts are measured

Measured in ohms

The unit of electrical resistance
