The royal utensils is model use 8ohm loudspeakers. With regard to have consuming trend low make use battery 9V get long moderately ago. The transformer T1 in a picture is model output transformer at use prevent general in the receiver transistor the general. Then help reduce the expenses in tool expensive buying. By the way will check to tell with sound signal which, pertaining to the expansion ratio of transistor. Checking Transistor with the sound This circuit uses to check transistor get accurately and fast. For switch S1 to switch the transistor is NPN or PNP. Therefore, the value must be multiplied by 10. The rate of increase (hfe) of the transistor.In position 3, the resistor at base pin will be lower than the 10 times (R1 = 56K). When S2 is in position 2 will be multiplied by a factor of 100. Which indicates that the transistor is also available. #BUKU PERSAMAAN IC DAN TRANSISTOR TESTING FULL#That is why the needle meter indicates full scale. When S3 is in position 2 is (6V-0.6V / 560K = approximately 10 micro-amps). This value can be calculated.By dividing the voltage drop across R1 or R2, with its resistance. When the transistor was tested.(S2 open, S3 is in position 2 or 3) The current will flow through the join junction base – emitter of the transistors were tested. Flow meter with a needle full scale, it is available. #BUKU PERSAMAAN IC DAN TRANSISTOR TESTING SERIES#This circuit have a simple way to work,In the test battery position (turn off switch S2).Moving coil meter 10 mA, in series with a resistance of 600 ohms(R4+R5).When connected to a battery, 6V, so the current 10mA(moving coil current). When not have time,or need to check the a lot equipment. Fast transistor tester circuits This circuit design, to determine quickly the transistors only. This circuit works you can watch video below. However you should check out the the circuit carefully. This circuit is very easy to use, so we use the peforated board, reducing the time to make this project a lot. Yazik programmirovaniya si kernigan ritchi pdf. The power Supply we use battery 9volt for this circuit has low current when measure in circuit. It use the nand gate digital CMOS or CD4011 or MC14011 or TC4011 so useful IC very low cost. Then place the probe and press s1, see the led indicator good or bad of the transistor easily.
