Sketch the symbals and label the leads for the two and three terminal devices
ZENER DIODE
Q2. Fill in the blanks
NPN.

LEDZENER DIODE
Q2. Fill in the blanks
Q3.
Q4: If V=IR and P=IV, what is P in terms of V and R
P=V2R
Vd = 0.7V. Diodes only require 0.7V to operate.
Vd = 0.7V. Diodes only require 0.7V to operate.
Q6, Vs=50V R1= 10Ohms Diode = 1W Max
Current Flow = (50-0.7)/10= 4.93 Amps
Q7, Pd=IdxVd Id=4.93, Vd=0.7 4.93 x 0.7 = 3.45W
Q8, Yes the diode will be destroyed. The maximum watt dissipation for the Diode is 1 watt and the total amount of watts this circuit will create on the diode will be too great for the diode to control.
Q9, Sketch a simple voltage regulator using discreet components
The zener diode acts as a 5V regulator, so any component placed on the same track as the zener diode will recieve 5V from the Zener Diode opposed from the 12v power supply.
Q10, Is the zener diode in the foward or reverse bias arrangement. Reverse
Not bad, the NPN drawing is not correct.
ReplyDeleteRemember a 10 ohm resistor is written as 10R.
