Question 4

1.    Technician A says the conventional theory of current flow states that current flows positive to negative. Technician B says current flows randomly. Who is correct?

1.    Both A and B

2.    B only

3.    A only

4.    Neither A nor B

Question 5

1.    What is voltage drop? 1.    Electrons used to go through a resistance 2.    Voltage used up when pushing current through a resistance 3.    Current used to go through a resistance 4.    All of the above

Question 6

1.    Technician A says when a magnetic field is moved across a conductor, voltage will be induced in the conductor. Technician B says when a conductor is moved across a magnetic field, voltage will be induced in the conductor. Who is correct? 1.    A only 2.    Both A and B 3.    B only 4.    Neither A nor B

• I m sorry here is the pohto • 1. What is the voltage drop across R3 = 12V

2. The source voltage

3. Req = 1/(1/4 + 1/6 + 1/8) = 1/(6/24 + 4/24+ 3/24) = 24/13 = 1.85Ω

4. Technician A says the conventional theory of current flow states that current flows positive to negative IS CORRECT. Technician B says current flows randomly is WRONG

5. #2 Voltage used up

6. #2 Both A and B

7. 1Ω
