Phantom or Fictitious Loading Method
While the capacity of meters under test is extremely high, testing with actual load method would includes a considerable loss of power and would not be economical too. Thus, to prevent wastage of power during testing, phantom load method is adopted. In these techniques, pressure circuit is supplied from a circuit of normal voltage source and the current circuit from a separate low voltage source. Therefore, total power consumed during testing becomes extremely small because of small pressure coil current at general voltage plus full load current at extremely less voltage for current circuit meter. Therefore, the meter under test in this condition simulates the full load condition through such phantom load kit.
Altavox is a manufacturer and distributor of a lot of electronic instruments and devices, including digital/analog multimeters, function generators, oscilloscopes, frequency counte
A four-pole, three-phase inductionmotor is energized from a 60-Hz supply. It is running at a load condition for which the slip is 0.03. Determine: (a) The rotor speed in r/min.
Refer to Figure 100. Assume MKS units. Given: R1= 4, R2=14, R3= 9, I4= 8, I5= 7. Determine: Ieq, Req, and V3.
Comparison of Analog-Modulation Systems The comparison of analog modulation systems (conventional AM, DSB SC, SSB SC, VSB, FM, and PM) can be based on three practical criteria:
a) What is meant by Ripple Voltage? Measure the Ripple Voltage Amplitude, Frequency and DC Offset b) Describe how Ripple Voltage could be decreased.
Design a DC motor control system to run the 48V DC motor at 40rpm up to max load of the motor. You are responsible for designing the control of a 24V supply along with the speed s
i need to talk to expert asap.
i need a counter of following o/p truth table 00000000 10000000 11000000 11100000 11110000 11111000 11111100 11111110 11111111 00000000 10000000 . . . so please suggest me some IC

What do you understand by DRAM and its refreshing? Dynamic RAM (DRAM) is fundamentally the same as SRAM, but this retains data for only 2 or 4 ms on an internal capacitor. But
