I really need some help with these Electronics questions. Please Help!!!?

Question

1. Express these two calculator displays in correct metric units: 5.6-07 2.2 05
a. 0.56 micro, 0.022 Meg
b. 56 micro, 22 kilo
c. 0.56 micro, 220 kilo
d. 56 micro, 220 kilo

2. What is the metric value of 16mA?

3. Which of the following terms are not a resistor rating?
a. resistor tolerance
b. resistor value in ohms
c. power rating
d. current

4. 500 milliA is equal to what?
a. 0.5 Amps
b. 0.0005 kA
c. 500,000 uA
d. all of the the above

5. Four resistors are connected in series across an 18 V source. Three resistors drop 0V, and one resistor drops 18 V. What's the trouble?
a. One resistor is open
b. The three resistors are open
c. Two of the resistors are shorted
d. There is no trouble: the voltages are normal

6. If each of the six resistors in a series circuit drops 5 V, the source voltage.....
a. equals 30 V
b. depends on the resistor values
c. equals 5 V
d. depends on the current

Answer 1

1. should be 560 nano; 220 kilo, but that's not a choice. The best choice is C, but write-in what I said for extra credit.

2. 0.016 Amp

3. D

4. D

5. A, But it depends on how you measure the voltages. The problem is you can't tell if 1 resistor is open or 3 resistors are open. This is a 'badly' formed question.

6. A

.

Answer 2

1:a
2:0.00000.16A
3:c
4:d
5:a
6:c
