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+

A two-level brightness intensity lamp circuit was made. A 12 W lamp was the load and the supply is selectable switched to either 3V or 6V to control the brightness. Prove mathematically that the lamp indeed receives lesser current during 3V than during 6V, causing it to lit less bright than during 6V supply. Hint: Keep the resistance of the lamp constant. Use ohm's law to prove it, and give a short written explanation to prove your solution.

150 100 + VA- a -4V AVA -7V 81. B b Figure 2 shows a simplified model of a gas-discharge lamp. One characteristic of these lamps is that they exhibit negative resistance; in other words, as current increases the voltage drops further, making such lamps inherently unstable. As such, a current-limiting ballast is required. For the connection shown in the figure: 1. Find the equivalent Thevenin circuit of the lamp. 2. Find the ballast resistance needed to limit the current drawn from a 24-volt source to 6 amperes.
