The Symmetrical Load Below Is Connected To A Three-phase Network. A Line Current Of 25A Has Been Measured.

Answers

Answer 1

Answer:

The line voltage of the three phase network is 346.41 V

Explanation:

Star Connected Load

Resistance, R₁ = R₂ = R₃ = 18 Ω

For a star connected load, the line current = the phase current, that is we have

[tex]I_L = 25 \, A = I_{Ph}[/tex]

Whereby the the voltage across each resistance = [tex]V_R[/tex] is given by the relation;

[tex]V_R[/tex] = [tex]I_{Ph}[/tex] × R

Hence;

[tex]V_{Ph}[/tex] = [tex]V_R[/tex] = [tex]I_{Ph}[/tex] × R  = 25 × 8 = 200 V

Therefore we have;

The line voltage, [tex]V_{L}[/tex] = √3 × [tex]V_{Ph}[/tex] = √3 × 200 = 346.41 V.

Hence, the line voltage of the three phase network = 346.41 V.

Answers

Question:

John read the first 114 pages of a novel, which was 3 pages less than ⅓ of the novel. Write an equation to determine the total number of pages (P)

Answer:

114 = ⅓P - 3

Explanation:

Given

Number of pages read = 114

Total pages in novel = p

The relationship between the pages read by John and the total pages is analysed as follows:

3 less than ⅓ of total pages means:

⅓ of total pages - 3

Recall that P represents the total pages in the novel

So, the expression becomes

⅓ * P - 3

⅓P - 3

This means that the pages read by John is ⅓P - 3

This implies that the equation to determine the number of pages in the novel is

⅓P - 3 = 114

Solving further to get the actual number of pages;

Multiply both sides by 3

3(⅓P - 3) = 114 * 3

3 * ⅓P - 3 * 3 = 114 * 3

P - 9 = 342

Add 9 to both sides

P - 9 + 9 = 342 + 9

P = 351

Hence the number of pages is 351

Answer:

Answers below

Explanation:

1. 114 = 1/3p - 3

2. 351 pages

2. Determining what materials can be used to make the
tacos.

3.Once the taco types are determined, making enough of them for everyone.

4.Making a few tacos and eating them to see how they taste.

Answers

Answer:

4. Making a few tacos and eating them to see how they taste.

Explanation:

The method of engineering design refers to the sequence of procedures that engineers undertake to reach a solution to a concerning problem. Generally,  the solution needs to create a machine or a product that fulfills specific requirements or performs a specific function. the step of testing and redesigning includes engineers to test their final design so that they can make change their solution to enhance it, based on their feedback and their experience with the solution. As per the question eating tacos will provide the appropriate feedback to make final changes to the tacos.
