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.

Answer:

hope you like it brainliest plezz

Explanation:

Tolerance equals the difference between lower and upper limit dimensions. Example; for 0.500-0.506 inch the tolerance would be 0.006 inch. BILATERAL TOLERANCE : It is a way to express tolerance by using both minus and plus variations from a given size.

Consider a rigid system containing water at 22 bars and 375°C:(1) Determine the phase at this condition, why?(2)Determine the sp
zavuch27 [327]

Answer and Explanation:

considering a  rigid  system

fixed volume V = C

water at P1=22bar and T1=375ºC

at 22 bar  Tsat =217.2ºC

so...

T1>Tsat

thus

Steam  is superheated      (phase at this condition)

Specific Volume, V1

V1= Vg * [ Tsup/Tsat]

V1= 0.090663* ((375+273)/(217.2+273))

V1= 0.1198 m³/kg   (specific volume under this condition)

V=C, T2=195ºC

from Mollier Diagram we have that..

P2= 6bar                         (quality and enthalpy)

h2= 2840 KJ/kg

Superheated Steam
