Give some applications of manganin.
Manganin is alloy of nickel, copper and manganese.
This is used shunts in measuring instruments, for making their coils and for making precision resistances.
Q. A 230-Vdc shuntmotor delivers 30 hp at the shaft at 1120 r/min. If the motor has an efficiency of 87% at this load, find: (a) The total input power. (b) The line current.
Q. What is Frequency Translation and Product Modulation? The basic operation needed to build modulators is the multiplication of two signals. Whenever sinusoids are multiplied,
A 3-kVA, 220:110-V, 60-Hz, single-phase transformer yields these test data: • Open-circuit test: 200 V, 1.4 A, 50 W • Short-circuit test: 4.5 V, 13.64 A, 30 W Determine th
List three characteristics of lines of magnetic flux
Define Time-Shifting Precedes Time-Reversing and Vice Versa Signal x[n] is time-shifted by m samples (delay in time) giving x[n - m]. This signal is then reversed at n = 0 givi
Experiment • Wire the circuit shown in Figure. Connect the three oscilloscope channels as shown in Figure. • Select the sinusoidal waveform. Adjust the frequency of the input volt
Q. A single-phase industrial plant consists of two loads in parallel: P1 = 48kW PF1 = 0.60 lagging P2 = 24kW PF2 = 0.96 leading It is operated from a 500-V, 60-Hz source.
Need for Modulation Recognition There are so many communication signals all available with different types of modulation and different frequencies. It is necessary to identify
There is a requirement to propose a new ASIC design flow within your company, from VHDL design capture through to GDSII tape out. It is very important that the flow includes all t
Write a program implementing the conjugate gradient method (un-preconditioned). Solve the matrix equation corresponding to a finite difference node-spacing, h = 0.02m in x and y di
