General knowledge of electronics

Electrical and Electronics are different but work with combine. electrical instrument genreal AC volt need but Electronics instrument or device working with Pure DC volt , small device require 1.5volt dc to 12 volt dc. basic calculation device output for getting watt capacity of device by “Watt = volt x current”, two types of supply need for device (1) direct ac code input in device, (2) via adaptor as per required (1.5 volt dc 100mA to 2amp, 3.0 volt dc 100mA to 2amp, till 36 volt 250mA to 10Amp).in indian supply is 230 volt AC 50 Hz so use input volt check for india 230volt AC must be required for connecting imported device,if foregn device input 110volt AC, in case of that use converter 230volt ac to 110volt AC than add this converter for used and working the best result we getting, using operating.

Care use toyes for children

There are many toyes need to dancing, running, jumping, need pencil cell, adoptor, codeless device, if need charging cell please must be proper charging from charging device, if no need to play with electronics device or toy remove cell or off switch from device for long time use of toyes life increase otherwise junk will be spreading between cell negetive polarity fitted spring will be loss. before any device operating please read manual book about its function, if device need ac code direct input device care to cable outer surface will be clean, otherwise shok to children who have no knowledge about main 230volt AC main 230volt AC supply.
