[♢ for delta]
R=V/I=100/10=10ohm
♢R/R=♢V/V +♢I/I = 5/100 + 0.2/100 = 7/100
♢R=0.07 × R =0.07 × 10 = 0.7ohms
percentage error =♢R/R × 100
= 0.7/10×100

Answer:

Explanation:[♢ for delta]

R=V/I=100/10=10ohm

♢R/R=♢V/V +♢I/I = 5/100 + 0.2/100 = 7/100

♢R=0.07 × R =0.07 × 10 = 0.7ohms

percentage error =♢R/R × 100

= 0.7/10×100

=7 %
