Mechanical Aptitude Test: Basic Electricity Concepts, Exams of Advanced Education

A concise overview of basic electricity concepts, ideal for mechanical aptitude test preparation. It covers conductors, circuits, power sources, and circuit types (series and parallel). Key definitions include conductor, wire, electrical circuit, power source, path, load, fuse, closed circuit, open circuit, filament, series circuit, parallel circuit, and short circuit. It explains how electricity travels, the function of a fuse, and the differences between series and parallel circuits. It also touches on short circuits and resistance.

Mechanical Aptitude Test ( Electricity)
Conductor - Answer- is any material that allows electricty to pass through it
Wire - Answer- is a good conductor
Wood/Non Metals - Answer- are bad conductors
Electricity Travels - Answer- in a circular path called a Circuit
Electrical Circuit/ Three Parts - Answer- Source, Path, Load
Power Source - Answer- electrical energy ( Ex. Battery or a Wall plug)
Path - Answer- electricity to follow (Ex. wires)
Load - Answer- Ex. Lightbulb, buzzer, or other electrical devices
Fuse - Answer- protects an electrical circuit against too much electrical flowing (Ex. Will
heat up/ burn and open the circuit and stop the electricity)
Two wires coming from a Power Source - Answer- may be called hot and ground or
positive & negative
Closed Circuit - Answer- all parts of the the circuit are connected
Open Circuit - Answer- at least one part is not connected
Electricity travels Pt 2. - Answer- through a closed circuit never through an open circuit
Filament - Answer- a small wire in a lightbulb that gets hot and gives of light
Two types of connections work - Answer- Series and Parallel Circuits ( to light up a
lightbulb)

Mechanical Aptitude Test ( Electricity)

Conductor - Answer- is any material that allows electricty to pass through it Wire - Answer- is a good conductor Wood/Non Metals - Answer- are bad conductors Electricity Travels - Answer- in a circular path called a Circuit Electrical Circuit/ Three Parts - Answer- Source, Path, Load Power Source - Answer- electrical energy ( Ex. Battery or a Wall plug) Path - Answer- electricity to follow (Ex. wires) Load - Answer- Ex. Lightbulb, buzzer, or other electrical devices Fuse - Answer- protects an electrical circuit against too much electrical flowing (Ex. Will heat up/ burn and open the circuit and stop the electricity) Two wires coming from a Power Source - Answer- may be called hot and ground or positive & negative Closed Circuit - Answer- all parts of the the circuit are connected Open Circuit - Answer- at least one part is not connected Electricity travels Pt 2. - Answer- through a closed circuit never through an open circuit Filament - Answer- a small wire in a lightbulb that gets hot and gives of light Two types of connections work - Answer- Series and Parallel Circuits ( to light up a lightbulb)

Series Circuit - Answer- electricity goes through all parts of the circuit ( take out any one part, the electrical path is broken ) Parallel Circuit - Answer- Has more than one electrical path ( you can take out one bulb and the others will still stay lit ) Short Circuit - Answer- the electricity flow without going through the load Electricity tends - Answer- take the path of least resistance ( ex. Wire) Lightbulb - Answer- is the load (higher resistance) Short Circuit pt 2. - Answer- usually happens when bare wires touch, wire is added in the wrong place, or there is a long wire.
