Computer Electronics Mr. Sciame

NAME: ______May 18, 2018 COMPUTER ELECTRONICS MR. SCIAME SECOND MARKING PERIOD, TEST 6, TAKE HOME

DIRECTIONS: Answer all 10 questions. It’s 100 points. Do all questions in the blue book provided. This is due on Tuesday Morning, January 2, 2007, at 7:50 AM. DO NOT PLACE THIS EXAM IN MY MAILBOX; hand it to me in person.

1. Fill in the following chart. Resistances should be whole numbers (1,000,000  or 1 M, and not in scientific notation. Band 1 Band 2 Band 3 Resistance Red White Blue Black Brown Black Red Black Orange Gray Gray Yellow Blue Yellow Red

2. Fill in the following chart:

Characteristic Series Circuit Parallel Circuit

The value of RT, when compared to individual R’s, is Greater or Less

VT = The largest R value has the MOST or LEAST power dissipation

PT is = to

3. Answer the following: P = 50W R = 2 ohms I = V = 40 V R = 16 ohms P = I = 5 amp R = 4 ohms P = P = 5000 W R = 8 ohms V = I = 20 milliamps R = 5 kilo ohms V =

4. You have plugged in a string of 24 IDENTICAL Christmas lights into a 120 V source. You test the current around one bulb and record the value as 0.5 A. If the string is connected in SERIES, find RT, PT, and the voltage drop, resistance, power dissipation, and current of the single light on that strand.

5. Refer to Page 140, figure 4-40. Find VT, RT, IT, PT, and the values of M1 and M3 in the diagram.

1 6. Fill in the chart below based on the following information for a parallel circuit.

V I R P T 30 V 1 4 k 2 12 k 3 10 k 4 30 k 5 30 k

7. Fill in the chart below based on the following information for a parallel circuit:

V I R P T 27.45 mA 1 12 ma 2 3 10 mA 1.8 k

8. Fill in the chart below based on the following information from a balanced Wheatstone Bridge:

R1 R2 Variable R3 RX 120  260  24  30  90  150  200  100  100  120 k 60 k 90 k 30  35  6 

9. Based on this crude attempt at drawing a circuit, determine the 3 load resistances, the total current, the individual resistances (R1, R2, and R3), and RT.

10. Refer to page 262, number 7. Construct a VIRP table and answer the question.
