Question

find the value of R of the circuit
if V =5v , I= 0.02mA​

Answer 1

Answer:

R=V/I

=5/0.02×10-3

=25×10^4

Answer 2

Answer:

Resistance, R=  

I V V=(8±0.5)V

           I=(4±0.2)A R=  I V  =  48

​  

=2Ω

We know from rules of error propagation.

R ΔR  =  V ΔV +  I ΔI =  8

0.5  +  

4 0.2 ​  

=0.1125

∴  % error =11.25%

⇒  R=(2±11.25)%
