Viator Vocab test 3.1.2 - 3.1.6

Electrical Energy

energy caused by the movement of charged particles

Current

the net transfer of electric charge (electron movement along a path) per unit of time. The symbol is I and the unit is ampere, which abbreviates to A

Voltage

the difference in electric potential between two points in an electric field

Resistance

the opposition that a device or material offers to the flow of direct current. The symbol is R and the unit is ohm, which is represented as Ω

Series Circuits

a circuit in which all parts are connected end to end to provide a single path of current

Parallel Circuits

an electrical circuit that has more than one path for current to flow

Nominal

a value that represents an approximation of a product characteristic and on which the acceptable tolerance is based

Electrical Circuits

a system of conductors and components forming a complete path for current to travel

Tolerance

the acceptable amount of dimensional variation that will still allow an object to function correctly

Equivalent Resistance

the total effect of all the resistors in the circuit

Branches

any portion of a circuit with two terminals connected to it

Nodes

the junction of two or more circuit branches

Momentary Switch

a switch that changes state only when pressed or held

Latching Switch

a switch that maintains its state after being activated

Reliability

consistently able to perform as expected
