1.

The resistant R=V/I where V=100+-0.5V and I=10+-0.2A. The percentage error in V is 5% and in I is 2%. Find the total percentage error is R.

Answer»


SOLUTION :DENSITY `=D+-DeltaD. DeltaD//D=Deltam//m+DeltaV//V=0.6//10+0.7//4.4=0.06+0.159=0.219`
`D=m//V =10//4.4=2.27.DeltaD=0.219xxD=0.219xx2.27=0.491` M
Density `=2.27+-0.491=(2.3+-0.5)GMC^(-3)`.
