RESISTOR / RESISTANCE

RESISOTOR:--RESISTOR IS THE VERY SMALL PART OF MOBILE.
ITS REAL SHAPE IN MOBILE PHONE IS BLACK BODY ANDSILVER
 LINE BOTH SIDE.
THERE ARE FIVE TYPES OF RESISTOR IN PHONE.

1).BLACK COLOR RSISTOR
2).PACKAGE RESISTOR
3).CHIP RESISTOR
4).FIX RESISTOR
5).VERRIABLE RESISTOR

VERIABLE RESISTOR ARE  THREE TYPES
a).LVR----LOW VALUE RESISTOR
b).HVR---HIGH VALUE RESISTOR
c).VDR---VOLTAGE DEPENDENT RESISTOR

OK TESTING OF RESISTOR -

SET M/M ON BUZZ MODE OR DIODE MODE -SET BOTH LEAD OF M/M ON BOTH SIDE OF RESISTOR IF BEEP SOUND THEN LVR RESISTOR IS OK -OK TESTINGOF HVR AND VDR  RESISTOR SET M/M ON OHM RANGE  TEST RESISTOR IF BOTH  SHOW SIDE SAME VALUE THEN RESISTOR IS OK IF NO BEEP OR BOTH SIDE DIFFRENT VALUE SHOWS THEN RESISTOR IS FAULTY
