Voltage, Current and Resistance - Engineering

Q1:

The maximum resistance value for a brown, red, yellow, gold resistor is

A 126,000 

B 126,600 

C 114,000 

D 132,000 

ANS:A - 126,000 

Brown 1, Red 2. Yellow 10^4, Gold +-5%.
The maximum value means + 5%.
12*10*10*10 * 10 = 120000,
120000*5/100 = 6000.
120000+6000 = 126000ohm.
