A current of 2mA is passed through a colour coded carbon resistor with first, second and third rings of yellow, green and orange colours. What isthe voltage drop across the resistor?
V=IR
I=0.002
R=45000(as yellow =4,green=5,orange=3 so 45*10'spower3)
V=0.002*45000
V=90V

Mahima answered this
but what happened to the fourth ring..shouldn't it be taken as tolerance for no ring...? that is plus or minus 20 percent...

Why we dont consider tolerance that is 20%
