Volt / Amp. Demonstration Meter Digital 

Digital Demonstration Meter DDM is a very useful sophisticated portable & rechargeable Giant Display unit for Demonstration of Voltage, Current, for more than hundred students at a time in a laboratory, class room & outdoor. Specifications: Display Rotation : Full rotation of 330° Something about Electronics : Electricity : Flow of electrons is called Electricity Conductor : All substance which allow electrons to flow is called Conductor Eg. All Ferrous (Metal contains IRON), BioMetals & Alloy (Combination of more than one metal), NonFerrous(Metal which does not contain IRON, such as Gold, Brass, Copper, & Aluminium Etc). are Good conductors Resistor / Insulator : All material which restrict or disallow the flow of electrons are called resistors/ Insulators Some of the important Equations related to Volt, Current, resistance & Power E =VOLTS ~or~ (V = VOLTS) P =WATTS ~or~ (W = WATTS) R = OHMS ~or~ (R = RESISTANCE) AMPS=WATTS÷VOLTS WATTS=VOLTS x AMPS VOLTS=WATTS ÷ AMPS I = P ÷ E P = E x I E = P ÷ I
