Basic Electricity For Gasfitters Flashcards
Sometimes referred to as hole flow. Current flow from the positive source to the negative source.
Conventional flow
The flow of electrons from a negative source to a positive source
Electron flow
For an electrical source, the force that maintains the difference in charge is called
Electromotive force
the unit of measurement for EMF
Volt
All electrical circuits need three components in order to work
A power source, a switch, a power consumer
An electrically operated switch
Relay
How to set an anticipator
Read the amp draw on the gas valve
Can be defined as an imbalance of electron distribution or charge difference between two points
Voltage
Is also known as electrical pressure?
Voltage
How to connect a voltmeter into a circuit
In parallel
The flow of electrons along a conductor is called what
Current
What is current measured in?
Amps
To measure your current, what must you do?
You must open the circuit and wire into it for this reason ensure the circuit is deenergized
This is defined as the opposition that a material offers to current flow due to its structure
Resistance
How is resistance measured?
Resistance is measured in ohms
And the circuit controls are wired into a single current conducting pathway one after another
Series circuit
The circuit has more than one current pathway each separate pathway can be controlled individually
Parallel circuit
This circuit series portion of the circuit controls the parallel circuit
Series/parallel
In this type of circuit, a series circuit is wired to another circuit in parallel with a common power source
Series and parallel
