Question 1 (16 marks) The table below gives the relation between deflection and mutual inductance of a dynamometer ammeter. The ammeter is designed so that 5 percent of a total current passes through the moving coil, and the remaining current passes through the fixed coil. Deflection (radian) 0 0.26 0.52 1.05 1.57 1.83 2.09 2.44 (full- scale) -325 -260 -180 0 180 263 325 373 Mutual Inductance (UH) If the total current that gives the full-scale deflection is = (the last TWO digits of your student ID =10) A, determine the following: (i) the torque required to give full-scale deflection. (ii) the current passing through the fixed coil at half-scale deflection. (Hint: Plot the graph of Mutual Inductance vs. Deflection based on the table above. Then, use the graph to solve the problem.) Question 1 (16 marks) The table below gives the relation between deflection and mutual inductance of a dynamometer ammeter.
