How much power is consumed by a 1.4A motor connected to a 12V battery?​

Computers and Technology

AleksAgata [21]3 years ago

Capacity

A battery's capacity determines roughly how long a battery will last at a specific voltage given a specific discharge rate. For example, if you choose a 12V, 2Ah (2000mAh) battery pack (regardless of chemistry), the battery should be able to run a 12V motor consuming 2A continuously for 1 hour. Alternatively, it can run a 12V motor consuming 1A for 2 hours, or a 12V motor consuming 0.5A for 4 hours. The rule of thumb is to divide the capacity (assuming you are running an actuator at the same voltage) by the actuator's current under normal load to get the time the motor will last.

What are the differences between tkinter toolkit and PyQt?
lesantik [10]

Answer:

See the explanation  

Explanation:

tkinter toolkit                                            

  • Easy to use
  • Easy to learn
  • Easy to debug
  • Good for simple tasks
  • TkInter applications are simpler as compared to PyQt because it is included in standard Python distribution.
  • Faster than PyQt.
  • Does not have advanced widgets.
  • No interface builder available.
  • Free for commercial utilization.

PyQt

  • More flexible in terms of coding.
  • Harder to debug as compared to tkinter
  • GUI is clearer in display than tkinter
  • Widgets are more interactive than that of tkinter
  • size of a PyQt program is larger than that of tkinter
  • uses a variety of paltform APIs and gives primary access to these APIs through a unique API.
  • Has an interface builder that allows to design interfaces without writing any code.
  • Has modern widgets.
  • Due to its vast interface and several UI components it is a bit confusing to learn as compared to tkinter.
  • Commercial license is required to release the code.
  • Cross-platform and native GUI.

Widgets are GUI components such as buttons, labels, menus.

a) Label

This is a tkinter widget to show the text or image on the screen. It looks like a display box. The user can easily edit or update label.

For example to display a label with text "Hello World" the following chunk of code is used:

import tkinter

widget = tkinter.Tk()

label =tkinter.Label(widget, text="Hello World")

label.pack()

tkinter.mainloop()

b) Entry

This is a tkinter widget to accept the text input from user. For example if you want to get a single line text from user then you can use Entry widget. The code below displays an entry widget with the message: Enter input text: Here the user can input the text.

import tkinter

widget = tkinter.Tk()

entry = tkinter.Entry(widget)

entry.insert(0, "Enter input text:")

entry.pack()

tkinter.mainloop()

c) Button

This is a tkinter widget to add a button in an application. You can enter some text or an image in this button convey its purpose. When you click on the button a function is called or an event is emitted.

The following chunk of code displays a button with the text "Click Me" on the button.

import tkinter

widget = tkinter.Tk()

button = tkinter.Button(widget, text="Click Me")

button.pack()

tkinter.mainloop()

d) Frame

This is a tkinter widget to group together and organize other widgets and arranges their position.

The following chunk of code displays an outer frame with a label with text "parent label" and an inner frame with a label of text "child frame".

import tkinter

widget = tkinter.Tk()

frame = tkinter.LabelFrame(widget,text="parent frame")  

label= tkinter.Label(frame,text="child frame")

frame.pack(padx=10, pady=10)

label.pack()

tkinter.mainloop()

(10 points) [Edhesive] 3.6 Code Practice
Digiron [165]

Answer:

  • You need to create a variable outside (before) the input loop.
  • You need a variable inside your loop that temporarily holds the user input.
  • In your loop, you will compare if the variable outside the loop is greater than (or less than) the new user input.

I don't know what program language you are using, but I will use python since it's easy to read and you will get the idea if you're using a different programming language.

<u>Code (Python)</u>

largestnum = 0

for x in range(6): <em>#loops 6 times</em>

   newnum = int(input("Enter a number: ")) #ask user for input & converts to int.

   if newnum > largestnum: <em>#if new number is greater than largest num </em>

     largestnum = newnum     <em>#make it the largest number</em>

<em>    </em>print("Largest:", largestnum)

The reason why you need a variable outside of the loop is because after the loop is done all variables inside the loop are trashed and can no longer be accessed outside of the loop.
