The pressure coil of a wattmeter should be connected on the supply side of the current coil when load impedance is high load impedance is low supply voltage is low none of the above 2. An induction wattmeter can be used for both D.C. and A.C. D.C. only A.C. only none of the above 3. In a 3-phase power measurement by two wattmeter method, both the watt meters had identical readings. The power factor of the load was unity 0.8 lagging 0.8 leading zero 4. In a low power factor wattmeter the pressure coil is connected to the supply side of the current coil to the load side of the current coil in any of the two meters at connection none of the above 5. The adjustment of position of shading bands, in an energy meter is done to provide friction compensation creep compensation braking torque none of the above 6. A dynamometer wattmeter can be used for both D.C. and A.C. D.C. only A.C. only none of the above 7. When a capacitor was connected to the terminal of ohmmeter, the pointer indicated a low resistance initially and then slowly came to infinity position. This shows that capacitor is short-circuited all right faulty 8. In a 3-phase power measurement by two wattmeter method the reading of one of the wattmeter was zero. The power factor of the load must be unity 0.5 0.3 zero 9. In a low power factor wattmeter the compensating coil is connected in series with current coil in parallel with current coil in series with pressure coil in parallel with pressure coil 10. An ohmmeter is a moving iron instrument moving coil instrument dynamometer instrument none of the above Time's up Share your love Facebook Twitter Pinterest Linkedin
