A new phlebotomist does not know anything about collecting a D-dimer or an HIV test. Where can the collection information on the

umka21 [38]

Answer: The information can be obtained from an expert phlebotomist or through an internet.

<u>Explanation:</u>

The Phlebotomist is one who is trained especially for taking out blood from the veins of patients. Such blood samples are used for testing purposes. If a phlebotomist is new and has no idea regarding collecting a D-dimer or an HIV test then in that case, he can take the help of another phlebotomist who is an expert in collecting such samples.

Such expert the phlebotomist will guide him properly in it. A new phlebotomist might read a book on such tests or can collect information from the internet also. This will resolve his problem.

n this example we will use the concept of equivalent resistance to determine the current in a circuit. Three identical resistors

belka [17]

Answer:

The answer is below

Explanation:

The complete question is in the iimage attached.

a) We can see that R1 is in series with the parallel combination of R2 and R3. Hence the equivalent resistance is given by:

$R_{eq}=R_1+(R_2//R_3)\\\\R_{eq}=R_1+\frac{R_2R_3}{R_2+R_3}\\ \\R_{eq}=6+\frac{6*6}{6+6}\\\\R_{eq}=6+3\\\\R_{eq}=9\ \Omega$

The current in the circuit (I) is given as:

I = emf / Req

I = 18 / 9

I = 2A

The current through resistor R1 = I1 = I = 2A

Since R2 and R3 are parallel to each other their respective currents I2 and I3 is given as:

$I_2=I*\frac{R_3}{R_2+R_3}=2*\frac{6}{6+6}=1\ A \\\\I_3=I*\frac{R_2}{R_2+R_3}=2*\frac{6}{6+6}=1\ A$
