A closed conducting path where charges flow
Electric circuit
Amount of charge passing through a point in a conductor per unit time
Current
Ampere is in honor of…
Andre-marie ampere
Current flow that changes directions at different intervals
Alternating current
Current that flows in one direction at all times
Direct current
From positive to negative
Convectional current flow
Negative to positive
Electron current flow
Volt is in honor of…
Allesandro volta
Opposition a material offers to the flow of charges through it
Resistance
Ohms is in honor of…
George simon ohm
Electrical components that implement electrical resistance as a circuit element
Resistors
The rate of transfer of energy within s circuit
Electric power
an electrical circuit that allows current to flow along an Unintended path with little or no electrical impedance.
Short circuit
when an electrical system, is subjected to a current higher than its
intended capacity.
Overloading
also known as a power sorge or transient voltage is a sudden increase in
voltage in an electric circuit
Electric surge
acts as a safety line to redirect
electric Current in the event of
short circuits.
Grounding
protects an electric circuit from excessive electric Current
Fuses
opens the cireuit if abnormal. current conditions occur, usually overloads but it is not destroyed in operation and can be closed again.
Circuit breaker
