In the circuit below, how many bulbs would light up if switch I were closed, and switch II was open? A. One B. Two C. Three D. Four E. NoneAnswer: the correct answer is C. If you close switch I and leave switch II open (see the red line in the drawing), you can see that...
The simple keyboard thin-film circuit board function test jig adopts the USB connecting cable to supply power, the changeover toggle switches are arranged according to a circuit diagram corresponding to the thin-film circuit board, and whether light-emitting diodes can normally emit light is ...
LCDs typically undergo functional and other tests at the end of their manufacture to detect substrates having defective light segments or dots. Among the tests normally performed is an open/short circuit test to detect open and short circuits in display signal lines. Generally, the open/short circ...
