Question

resistance is given by r v/1. if v=10+-5V and 1 =10+-2A find persentage error of R​

Answer 1

Answer:

The point \( \left( {{x}_{0}}+\frac{1}{p\left( {{x}_{0}} \right)}\ ,\ \frac{q\left( {{x}_{0}} \right)}{p\left( {{x}_{0}} \right)} \right) \) is located

Answer 2

Answer: So, percentage error in resistance (R) = +- 7%.

Explanation: Hey!

As we know,  resistance is the ratio of voltage used and current flowing through the circuit. So,

R = V/I

By error calculation (division formula)

DeltaR/R = [(Delta V) /V] *100 +[(delta I) /I] *100

= (5/100)*100 + (0.2/10)*100

= 5 + 2

=7%

So, percentage error in resistance (R) = +- 7%.

Hope it helped to clear your delimma.
