Time of onset: In Jamaica, it begins one to 2 hours after death and takes further one to 2 hours to develop. In temperate countries, it begins in 3 to 6 hours and takes further 2 to 3 hours to develop. Duration of rigor mortis: In Jamaica, usually it lasts 18 to 24 hours in winter and 12 to 18 hours in summer.
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Electromagnetic induction produces an electromotive force across a conductor which is exposed to time varying magnetic fields.ccording to Faraday's law of induction, since the same magnetic flux passes through both the primary and secondary windings in an ideal transformer, a voltage is induced in each winding, according to eq. (1) in the secondary winding case, according to eq.
A transistor is a three-terminal electronic component composed of semiconducting material such as silicon or germanium.   the purpose of a transistor is to use a small sign â¦ al to vary the conductivity of a piece of semiconductor.The tiny signal can switch a large current on and off. Or, the signal can be used to control a larger signal, so the transistor becomes an amplifier.ecause in this device the resistsnce between two terminale respectively collector and emitter is changed by changing the base voltage that is it transfers the resistance betw â¦ een emitter and collector therefore it is called as TRANSISTOR.(TRANSFER OF RESISTOR) Not exactly. Name.
