1.	A voltage of 5 V is applied across a colour coded carbon resistor. A current of 5 mA flows through it. What are the colours of second and third band of coded colour resistor?
Answer» Here, `V=5V, I=5 mA = 5 xx 10^(-3)A` Resistance of carbon resistor, `R=V/I=5/(5xx10^(-3)) =10^(3)Omega =10 xx 10^(2)Omega` Therefore, the colours of second and third bands will be related to numbers 0 and 2,i.e., black and red.
