An ammeter with a full scale deflection of 10mA has an internal resistance 0.5\(\Omega\). calculate the resistance of the shunt required to adapt it to read up to 3A
-
0.0167\(\Omega\)
- 0.0130\(\Omega\)
- 0.0250\(\Omega\)
- 0.1000\(\Omega\)
The correct answer is: A
Explanation
\(R_2 = \frac{I_1R_1}{I_2} = \frac{0.01 \times 5}{2.99}\)= 0.0167
