Ammeters

is a measuring instrument used to measure the electric current in a circuit.

The majority of ammeters are either connected in series with the circuitcarrying the current to be measured (for small fractional amperes), or have

their shunt resistors connected similarly in series.

Auto transformer

(sometimes called auto step down transformer) is an electrical transformer

with only one winding. frequently used inpowerapplications to interconnect systems operating at

different voltage classes; used to adapt speakers to constant-voltage audio

distribution systems; used for providing conversions between the twocommon domestic mains voltage bands in the world

electrode. it is primarily used in the classroom to demonstrate how batteries work.

Multimeter

also known as a VOM (Volt-Ohm meter), is an electronicmeasuring instrumentthat combines several measurement functions in one unit.

can be a hand-held device useful for basic fault finding and field servicework, or abench instrument which can measure to a very high degree of

accuracy.

Electric motor

is an electric machine that converts electrical energy into mechanical energy. found in applications as diverse as industrial fans, blowers and pumps,

machine tools, household appliances, power tools, and disk drives, electric

motors can be powered by direct current (DC) sources, such as frombatteries, motor vehicles or rectifiers, or by alternating current (AC) sources,

such as from the power grid, inverters or generators.

Copper Wire used in electric wiring since the invention of the electromagnet and the

telegraph in the 1820s. used in power generation, power transmission, power distribution,

telecommunications, electronics circuitry, and countless types of electricalequipment.

Crocodile Clips

also alligator clip or spring clip) is a simple mechanical device for creating a

temporary electrical connection, and is named for its resemblance to analligator's or crocodile's jaws.

functioning much like a spring-loaded clothespin, the clip's tapered,

serrated jaws are forced together by a spring to grip an object
