The area of this rectangle is 3x2 what does the coefficient 3 mean in term of the problem
tangare [24]
By definition, the area of a rectangle is given by:
 A = (w) * (l)
 Where,
 w: width
 l: long
 For this case, we have that the area is given by:
 A = (3) * (2)
 Therefore, in terms of this problem, the coefficient 3 represents one of the dimensions of the rectangle.
 Answer:
 
The coefficient represents one of the dimensions of the rectangle.

The total source voltage in the circuit is 6-3i V. What is the voltage at the middle source
Bezzdna [24]

Answer:

<em>The voltage at the middle source is</em> (2-4\mathbf{i})\ V

Step-by-step explanation:

<u>Voltage Sources in Series</u>

When two or more voltage sources are connected in series, the total voltage is the sum of the individual voltages of each source.

The figure shown has three voltage sources of values:

2 + 6\mathbf{i}

a + b\mathbf{i}

2 - 5\mathbf{i}

The sum of these voltages is:

V_t=4+a+(6+b-5)\mathbf{i}

Operating:

V_t=4+a+(1+b)\mathbf{i}

We know the total voltage is 6-3\mathbf{i}, thus:

4+a+(1+b)\mathbf{i}=6-3\mathbf{i}

Equating the real parts and the imaginary parts independently:

4+a=6

1+b=-3

Solving each equation:

a = 2

b = -4

The voltage at the middle source is (2-4\mathbf{i})\ V
