Part III – The Workshop

I. Identifying basic TOOLS and EQUIPMENT for circuit work

1. This is a zippered carry case containing the basic electronic tool kit for both – the electronics professional or hobbiest.

Label the picture with the expressions from the box.

wire cutters multimeter long nose pliers wire strippers proto board screwdriver

2. Match the items on the left with the definitions on the right.

TOOL / INSTRUMENT

USE

Long nose pliers measure voltage, current and resistance.Wire strippers IS / ARE solder the components to a printed circuit board.Wire cutters USED TO cut wire to a particular length.Soldering iron strip the end of wire, removing the insulation part, leaving

the copper.Multimeter hold wire while it is been cut or to hold small components.

II. Identifying ELECTRONIC COMPONENTS

1. Label the pictures with the expressions from the box.

diode transistor resistor capacitor LED diode

2. Complete the definitions of electronic components.

a. A …………………………… is a semiconductor device which amplifies current.b. A …………………………… is a two-terminal component which restricts the flow of current.c. A …………………………… is a passive electronic component which stores electric charge.d. A ……………………...…… is a device which only allows current to flow in one direction. e. A ……………………...…… is a transducer which converts electrical energy to light.

III. SOLDERING

1. DefinitionSoldering is a process in which two or more metal items are joined together by melting and flowing a filler metal (solder) into the joint.

2. Tools Label the picture →soldering ironsoldering iron standspongewire strippersswitch

3. How to solder

a. Complete the SOLDERING GUIDE (the first letter of the word may help you) .

4. Interactive exercise - Soldering http://www2.arnes.si/~sspmsubi/soldering2.htmIV. Creating MY FIRST IC

1. Below is a picture of a solderless breadboard ZY-204 with the attached components. You created this IC during your workshop.

a. Label the picture with the following expressions: b. Draw the diagram of your IC.resistor, LED diode, proto board, microchip, switch ↓

2. Below are the diagrams of the first integrated circuit (pic. in Part I) created by Jack Kilby.

a. Label the picture on the left with components and compare Kilby’s IC and diagram to yours. Use and / but / however.

3. Series circuit or parallel circuit?

Circuits are generally very complex combinations of series and parallel circuits.Have the components in your circuit been connected in series (along a single path, so the same current flows through all the components) or in parallel (the same voltage is applied to each component)?

Answer: ________________________________________________________________

Think of a string of Christmas lights. If any of the bulbs is missing or burned out, no current will flow and none of the lights will go on. Which circuit has been used – series or parallel?

4. HOMEWORK
