Question 203Electricity & Electronics - 1st Asst/Chief

The correct answer is A) 1, which represents a PNP type bipolar junction transistor. The illustration EL-0065 shows the standard electrical symbols for various electronic components, and the symbol labeled 1 is the correct representation of a PNP bipolar junction transistor. This is in accordance with the standard electrical schematic conventions used in the US Coast Guard Captain's License Examinations. The other options, B) 2, C) 3, and D) 4, represent different electronic components such as an NPN transistor, a diode, and a resistor, respectively, and are not the correct symbol for a PNP bipolar junction transistor.
