A current carrying conductor obeys Ohm's law (V=R I) . If the current passing through the conductor is I=(5 0.2) A and voltage developed is V=(60 6) V , then find the percentage of error is resistance, R
Options
- A18
- B6
- C14
- D2
Correct answer
C. 14
Step-by-step solution
Given, current passing through the conductor, I=(5 0.2) A , I=0.2 ~A Voltage developed, array rlrl & & V & =(60 6) V & V & =6 ~V array By Ohm's law, aligned V & =R I R & = V I R R & = V V + I I & = 6 60 + 0.2 5 & =0.1+0.04 R R & =0.14 R R 100 & =0.14 100=14 % aligned
