Electrical Terminologies Flashcards
Also known as electric potential is the electrical pressure
Voltage
Is the flow of electric charge (usually electrons)
Current
Is a property of a material that opposes the flow of electrical curren
Resistance
Is a closed loop or path through which electricity flows
Circuit
Is a material that allows the easy flow of electrical current
Conductor
Is a material the does not allow the flow of electrical current
Insulator
Is a graphical representation of an electrical circuit using symbol
Circuit diagram
This is known as conventional cyrrent representing the flow of positive charge
Conventional
In reality electrons are negatively charge and move from the volatage source negative
Electron flow
Is a type of electric current characterized by the constant flow of electric charge in asingle direction
Direct current
Is an electrical current that reverses direction
Alternating vurrent
Is the number of cycles per second in an ac wave from measured ing heartz
Frequency (f)
Is a device that provides a vonstant voltage to a circuit such as batteries or power supply
Volatage source
Is a device that provides a constant current to a circuit used in specialized application
Current source
Is a passive electronic component that limits the flow of current in a circuit
Resistor
It is often used to control current or divide voltage
Resistor
Stores electrical energy in an electric field and is used in circuits for function like energy storage and filterring
Capacitor
Stores electrical energy in amagnetic field
Inductor
Is an electrical device that can change the voltage
Transformer
Is reference point in electrical circuits often used as a zero voltages
Ground(earth)
Occurs when there is a break in the path preventing the flow of current
Open circuit
Refers to an electrical circuit where there is complete uninterrupted path
Closed circuit
Occurs when an unintended low resistant path is created in a circuit
Short circuit
This refers to measure taken in circuit and devices to prevent or mitigate
Short circuit protection
Components are connected end to end
Series circuit
Components are connected across common points so they share the same voltage but have different curren
Parallel circuit
