What is the function of a fixed resistor?

Engineering
1 answer:
agasfer [191]3 years ago
8 0

Answer:

  add resistance to a circuit

Explanation:

It depends on the design in which it is incorporated. A fixed resistor has many uses, including, but not limited to ...

  • dropping voltage
  • limiting current
  • contributing to a time delay
  • adjusting frequency response
  • eliminating (or creating) signal reflections
  • acting as a fuse
  • calibrating or trimming a response
  • providing protection against electrical shock or ESD
  • acting as a reference when measuring variable resistors

Sum of Numbers Design a function that accepts an integer argument and returns the sum of all the integers from 1 up to the numbe
cestrela7 [59]

Answer:

# define main to get an argument from the user, call the function, and display the final values

def main():

 # ask an argument from the user.

 number = int(input('Enter a positive integer: '))

 # solve the integral thing of the number by putting the user's argument in the addition() function

 finalSum = addition(number)

 # display the final value integral thing

 print("The integral of this number is ", finalSum, ".")

# define an addition function to find the integral

def addition(num):

 # make an if-statement to test filter things out of your calculations. In this case, 1.

 if num == 1:

   #if 1, return 1. because 1 + (1 - 1) = 1

   return 1

 # this is where the recursion actually is. This is the part that calculates

 else:

   return num + addition(num-1)

# call your main function

main()

This is written in Python. A link to the output can be found below.

If you've wondered about the flushing of toilets on the upper floors of city skyscrapers, how do you suppose the plumbing is des
Marina86 [1]

Answer:

<em>The plumbing is designed to reduce the impact of pressure forces due to the height of skyscrapers. This is achieves by narrowing down the pipe down to the basement, using pipes with thicker walls down the basement, and allowing vents; to prevent clogging of the pipes.</em>

<em></em>

Explanation:

<em>Pressure increases with depth and density</em>. In skyscrapers, a huge problem arises due to the very tall height of most skyscrapers. Also, sewage slug coming down has an increased density when compared to that of water, and these two factors can't be manipulated. The only option is to manipulate the pipe design. <em>Pipes in skyscrapers are narrowed down with height, to reduce accumulation at the bottom basement before going to the sewage tank. Standard vents are provided along the pipes, to prevent clogging of the pipes, and pipes with thicker walls are used as you go down the basement of the skyscraper, to withstand the pressure of the sewage coming down the pipes.</em>

Viteza unui mobil care se deplasează cu accelerație constantă crește de la 3,2 m/s la 5,2 m/s în timp de 8 s. Accelerația mobilu
Verizon [17]

Answer:

a=0.25\ m/s^2

Explanation:

Initial speed of the mobile = 3.2 m/s

Final speed of the mobile = 5.2 m/s

Time, t = 8 s

We need to find the acceleration of the mobile. It can be given by the change in velocity divided by time. So,

a=\dfrac{v-u}{t}\\\\a=\dfrac{(5.2-3.2)\ m/s}{8\ s}\\\\=0.25\ m/s^2

So, the acceleration of the mobile is 0.25\ m/s^2.

A 75 ! coaxial transmission line has a length of 2.0 cm and is terminated with a load impedance of 37.5 j75 !. If the relative p
Cerrena [4.2K]

Answer:

4.26

Explanation:

The wavelength λ is given by:

\lambda=v/f=c/nf\\c=speed\ of\ light=3*10^8m/s,f=frequency=3*10^9Hz,n=permittivity=2.56\\\\\lambda=3*10^8/(2.56*3*10^9)=0.0625\ m\\

Phase constant (β) = 2π/λ

βl = 2π/λ × l

l = 2 cm = 0.02 m

βl = 2π/0.0625 × 0.02=2.01 rad = 115.3°

1 rad = 180/π degrees

Z_L=load\ impedance=37.5+j75\\\\Z_o=characteristic impedance = 75\ ohm\\\\\tilde {Z_L}=Z_L/Z_o=37.5+j75/75=0.5+j

\tilde {Z_{in}}=\frac{\tilde {Z_{L}}+jtan\beta l}{1+j\tilde {Z_{L}}tan\beta l}=\frac{0.5+j+jtan(115.2)}{1+j(0.5+j)tan(115.2)}=0.253-j0.274\\  \\Z_{in}=Z_o\tilde {Z_{in}}=75(0.253-j0.274)=19-j20.5\\\\\Gamma_L=\frac{Z_L-Z_0}{Z_L+Z_o}=\frac{37.5+j75-75}{37.5+j75+75}=0.62\angle 83^o\\\\\Gamma_{in}=\frac{Z_{in}-Z_0}{Z_{in}+Z_o}=\frac{19-j20.5-75}{19-j20.5+75}=0.62\angle -147^o\\\\VSWR=\frac{1+\rho}{1-\rho} =\frac{1+0.62}{1-0.62}=4.26

What is the function of the following: 1- Oil rings 2- Flywheel 3- Timing gears
Tanya [424]

Answer:

Explanation:

The functions of the following are as follows:

1). Oil Rings:

  • Regulates oil within cylinder walls.
  • Helps to keep cylinder walls lubricated
  • Prevent Heat transfer
  • Reduce friction between piston and cylinder

2). Fly Wheel:

  • It is used to store rotational energy
  • It resist any change in rotational speed due to its moment of inertia
  • It helps to control the orientation of the mechanical system

3). Timing gears:

  • It provides synchronization in the rotation of crankshaft and the camshaft so as to provide proper valve opening and closing time during each cylinder's stroke(intake and exhaust).
