Each question presents a situation and asks you to make a judgement regarding that particular circumstance. Choose an answer based on given information. Arun, Varun and Tarun were performing an experiment in a Chemistry lab. In the experiment they have to mark down the reading for the exam. The reading is displayed only for few seconds on ABC-meter. Each of them watched the reading and remember certain numbers. The reading is of eight digits. Out of all three, if at least two agrees for a digit then that digit must be present in the reading. 1. All three of them agrees that last 3 digits were 754. 2. Varun mentioned that the 5th digit from the left was 7. 3. Tarun and Arun agrees that first two digit from left was 35. 4. Varun and Tarun agrees that 4th digits was average of 3rd and 5th digit from the left. Which of the following would be most likely the reading of the experiment?
In the Two wattmeter method of measuring power in a balanced three-phase circuit, one wattmeter shows zero and the other positive maximum. The load power factor is?
In the Two wattmeter method of measuring power in a balanced three-phase circuit, one wattmeter shows zero and the other positive maximum. The load power factor is ___________
A single wattmeter is connected to measure the reactive power of a three-phase, three-wire balanced load. The line current is 17A and the line voltage is 440V. Calculate the power factor of the load if the reading of the wattmeter is 4488 VAR.
Which of the following statements are true? a. As load increases armature current decreases, regardless of excitation. b. For under and over excited motors, power factor tends to approach zero with increase in load c. With normal excitation when load is increased, change in armature current is greater than in power factor which tends to become increasingly leading. d. Both with under and over excitation, change in power factor is greater than in armature current with increase in load.
Which power factor results equal reading of both wattmeter in 2 wattmeter method -
The wattmeter method is used to measure power in a three-phase load. The wattmeter readings are 400W and -35W. Find the power factor.
A – 3 phase balanced load which has a power factor of 0.707 is connected to balanced supply. The power consumed by the load is 5 kW. The power is measured by the two-wattmeter method. The readings of the two watt meters are.
The input power to a three-phase load is 10kW at 0.8 Pf. Two watt meters are connected to measure the power. Find the reading of higher reading wattmeter.
