The voltage across a load is 200 V and the current flowing through it is 50 A at a lagging power factor of 0.8. The wattmeter used to measure the power consumed by the load is connected such that its current is in series order with the coil load and the voltage is at full load in the side of the coil load. The resistances of electric current and voltage coils are 0.01 Ω and 1000 Ω respectively. What will be the reading of the wattmeter? |

| B. | 8040 W |
| C. | 8400 W |
| D. | 4400 W |
| Answer» C. 8400 W | |
