ScienceWiz(R) Electronics, Voltage, Current & Resistance: Would you like to build your own LIE DETECTOR? With ScienceWiz(R) Electronics -- you do exactly that. First, there are few basic concepts to learn. The kit includes both a multimeter and all the electronic components needed to build multiple circuits. With Electronics you go from making potato batteries and voltage piles to building your first electrical circuits. You begin by using a multimeter:



to measure the voltages of batteries, new and usedto measure the current in potato batteries connected in series and parallelto determine the value of the resistor used to protect an LED from being fried by a nine volt battery.to solve circuit puzzles to use as a continuity tester

In so doing, you are preparing to build and more importantly debug actual circuits. Then on to building your first electronic circuits:

a touch sensora simple oscillator that flickers an LEDlight-blinking circuitsand finally, of course, a LIE DETECTORThe first circuit has three electronic components. The second one introduces one more component and so on. The kit includes a breadboard and uses zero ohm resistors as connecting wires, so no soldering is required. This book introduces the curious of all ages to a fundamental set of concepts and skills necessary for not only building electronic circuits but also for building and repairing robots, household wiring and even electric vehicles. The list of applications is very long, indeed. It includes a 48 page book, a multimeter, components necessary to build each electronic circuit, a buzzer, a motor, test leads, alligator clips, a nine volt battery cap, a bread board and zero ohm resistors to use as connecting wires on the breadboard.
