Determine the shunt resistance needed to convert a galvanometer to an ammeter with a full scale reading of 10A if the scale requires 2.5mAto cause full deflection with a coil resistance of 10Ω.
A voltage divider can provide a voltage at its output, but it cannot provide current. If a device is connected to the output of a voltage divider, what value of resistance should it have
a) Draw a sketch of the spectrum of x(t) = sin3(400πt) Label the frequencies and complex amplitudes of each component. Determine the minimum sampling rate that can be used to sample x(t) without aliasing for any its components.
Consider the following differential equation, where x(t) is the input and y(t) is the output: d/dt y(t)+5y(t)=2x(t) Suppose the input is x(t) = 4u(t) and the initial condition is y(0-) = 6 1. What is the impulse response for the system
An Amplifier hasa low pass STC frequency response. the magnitude of the gain is 20dB at dc and 0dB at 100KHz. What is the Corner frequency At what frequency is the gain 19dB At what frequency is the phase -6degrees
An FM receiver is modulated with a signal having a baseband bandwidth of 15 kHz and the maximum frequency deviation is 45 kHz. Assume that preemphasis is added with a 3-dB boost frequency of 5 kHz.
A residential four-wire system supplies power at 220V rms to the following single-phase appliances: On the first phase, there are ten 75-W bulbs. On the second phase, there is a 750-W vacuum cleaner with a power factor of 0.87.
when the load is removed from the generatorthe magnitude of the terminal voltage is 34500V. the generator feeds a delta-connected load through a transmission line with an impedence of 0.8+j6.4. the per-phase impedence of the load is2877-j864.
what is meant by "proactive" project management. Discuss ways in which to ensure that projects are being managed proactively. Investigate on the internet the features of Microsoft Project. Discuss why a project plan is not a Microsoft Project file.
From the 1H NMR perspective, the human body is composed primarily of fat hydrogens and water hydrogens (H2O). The resonance frequency difference between the NMR signal from these two types of hydrogens is approximately 220 Hz on a 1.5 Tesla imager..
Provide an output V to indicate that at least one of theinputs is present. The input with the highest subscript number has the highest priority. What will be the value of the four outputs if inputs D2 and D6 are 1 at the same time
How fast, in rpm, would a 100 g, 50-cm diameter beach ball have to spin to have an angular momentum of 0.10 kg m^2/s
A GaAs device is dopeed with a donor concentration of 3*10^15 cm^-3, For the device to operate properly, the intrinsic carrier cconcentration must remain less than 5 percent of the total electron concentration.
