The resistance R = V//i, where V = 100 +...

The resistance `R = V//i`, where `V = 100 +- 5 V and I = 10+- 0.2 A`. What is the total error in `R`?

A

0.05

B

0.07

C

0.052

D

`((5)/(2))%`

Text Solution

Verified by Experts

`R=(V)/(T)`
`(DeltaR)/(R)=(DeltaV)/(V)+(Deltal)/(l)=((5)/(100)xx100+(0.2)/(10)xx100)%`
`=7%`
