In the figure below you see the sketches for the front and back of an electrical circuit board. The board is cut into a trapezoidal shape and is made of plastic. On the back of the board there is conductive paint shown here in green. On the front there are some resistors and capacitors, in addition to terminals for inserting the leads from a DC power supply. The legs of the resistors and capacitors go through the holes on the board and are soldered to the conducting paint on the back side. You also have a multi-meter which you can use as an ammeter or a voltmeter. 16 v 4700 16 10 8 O- 7 3. 6. 4 O+
