you have a 10vdg source available design a voltage divider ciruit that has 2 vdc , 5vdc , and 8 vdc available the total circuit current is to be 2mA
Answers
If you try to divide 10V in three voltages, the sum of the three voltages must be equal to the total voltage source, in this case 10V. Having said this, 2 + 5 + 8 = 15V, and your source is only 10V. So you can see is not feasible. You can, for example, have 2V, 5V and 3V, and the sum is equal to 10V. Before designing the circuit, i.e, choosing the resistors, you need to understand this. Otherwise, I suggest you to review the voltage divider theory.
For instance, see IMG2 in my previous post. If we were to design a single voltage divider for the 5VDC, i.e, 50% of the 10V source, you generally choose R1 = R2., and that would be the design equation.

Click on one or a lot of cells that you want to make use of as the basis that is needed for filling additional cells. For a set such as 1, 2, 3, 4, 5..., make sure to type 1 and 2 into the 1st two cells. Then pull the fill handle .If required, select Auto Fill Options. and select the option you want.How do you make a group of cells auto-fill?The first thing to do is to place the mouse pointer over the cell's bottom right corner and hold it there until a black + symbol appears. Drag the + symbol over the cells you wish to fill in while clicking and holding down the left mouse button. Additionally, the AutoFill tool rightly fills up the series for you.
Note that Excel data entering can be automated and this can be done by: On the Data tab, select "Data Validation," then click "Data Validation." In the Allow box, select "List." Enter your list items in the Source box, separating them with commas. To add the list, click "OK." If you wish to copy the list along the column, use the Fill Handle.

Answers
Answer:
Explanation: How to calculate fuel economy and usage
Manufacturers give a fuel economy figure for new cars in litres per 100km for urban, extra urban (i.e. higher speeds) and combined (a mixture of the two). This number is determined via a standardised test which, unfortunately, bears very little resemblance to the type of driving the vast majority of people do. If a vehicle you are looking at purchasing has an indicated fuel economy of 8l/100km, everyday driving is probably more likely to be around 10l/100km (this is my experience, after driving and reviewing over 400 cars since 2007).
However, the manufacturer-supplied figures are good for comparing between models, just not calculating what your expected fuel costs will be.
