How do we find percentage error in measuring voltage across a resistor​
Black_prince [1.1K]

Answer:

  use the percentage error relation

Explanation:

The percentage error in anything is computed from ...

  %error = ((measured value)/(accurate value) -1) × 100%

__

The difficulty with voltage measurements is that the "accurate value" may be hard to determine. It can be computed from the nominal values of circuit components, but there is no guarantee that the components actually have those values.

Likewise, the measuring device may have errors. It may or may not be calibrated against some standard, but even measurement standards have some range of possible error.

Make Routh tables and tell how many roots of the following two polynomials are in the right half plane and in the left half plan
12345 [234]

Answer:  

P(s) = s5 + 3s4 + 5s3 + 4s2 + s

For above Polynomial, there are two RHP Poles & Three LHP Poles.

& for the Second Polynomial,

P(s)=3s7 + 9s6 + 6s5 + 4s4 + 7s3 + 8s2 + 2s + 6

For this Polynomial, there are Four RHP Poles & Three LHP Poles.

Explanation:

As the equation is given by for the first polynomial,

P(s)=s5 + 3s4 + 5s3 + 4s2 + s

The Routh table is attached in the attachment, & from that table we can see that there are two sign changes for thuis first ploynomial. Moreover, there are two RHP poles & Three LHP Poles.

Similarly the equation for the second polynomial is given by as,

P(s)=3s7 + 9s6 + 6s5 + 4s4 + 7s3 + 8s2 + 2s + 6

The Routh Table is attached in the same attachment below in the 2nd slide & from this table we can see that there are four sign changes for this polynomial while it includes Four RHP Poles & three LHP Poles.

Conversion of a continuous stream of sound into a series of ones and zeroes that can be interpreted by computers results in
gayaneshka [121]

Answer:

Conversion of a continuous stream of sound into a series of ones and zeroes that can be interpreted by computers results in  digital audio.

Explanation:

Digital audio is a portrayal of sound recorded in, or changed over into, digital structure. In digital audio, the sound flood of the audio signal is encoded as numerical examples in a persistent arrangement. In a digital audio framework, a simple electrical sign speaking to the sound is changed over with a analog-to-digital converter (ADC) into a digital sign, regularly utilizing beat code adjustment. This digital sign would then be able to be recorded, altered, adjusted, and replicated utilizing PCs, audio playback machines, and other digital apparatuses. At the point when the sound specialist wishes to tune in to the account on earphones or amplifiers (or when a shopper wishes to tune in to a digital sound record), a digital-to-analog converter (DAC) plays out the opposite procedure, changing over a digital sign go into a simple sign, which is then sent through an audio power intensifier and at last to an amplifier. Digital audio is an innovation that is utilized to record, store, control, create and repeat sound utilizing audio flags that have been encoded in digital structure. It likewise alludes to the grouping of attentive examples that are taken from a simple audio waveform. Rather than a consistent sinusoidal wave, digital audio is made out of careful focuses which speak to the sufficiency of the waveform roughly. The more examples taken, the better the portrayal, and henceforth impacts the nature of the digital audio. Most present day sight and sound gadgets can just process digital audio, and on account of mobile phones requiring simple audio input, they despite everything convert it to digital before transmission.
