A 1.2k resistor has a tolerance of 10%. Its
resistance value will lie between
The answer is :- 3 Tolerance is a measure of the maximum
error in the stated value. Thus a 10% tolerance means the
component value could be as much as 10% higher or lower than
that stated. In this case the maximum error will be 10% of
1200, i.e. 120
. Thus the actual component value may lie
anywhere between 1200+10% and 1200-10%. Lowest value = 1200-10%
= 1200-120 = 1080 = 1.08k
. Highest value = 1200+10% = 1200+120 =
1320 = 1.32k
