After seeing the presentation of Unit 1 answer the following questions and answer back in the notebook (you'll recall that I gave up 10 in a photocopy)
EXERCISES UD 1
1. Difference between atom, ion, cationic, anionic
2. Explains the attraction or repulsion between charges.
3. DEFINE:
a. DRIVER
b. INSULATION
4. ELECTRICAL defines and explains
If you imagine a conductor formed by a row of copper atoms, and connected to the pile driver, explains why there are free electrons in the conductor are less than the pole pole again, and do not follow another way.
5. ELEMENTS IN A CIRCUIT: symbol explanation.
6. Explains that it is an electrical circuit as electrons moving.
carry a sense, that is negative to the positive pole
. Answer these questions:
a) What is the name that sense of power?
b) How is called the opposite?
7. GENERATOR: explains how, help yourself with a picture.
8. RECEIVER: explains how, help yourself with a picture.
9. Electric charge: definition and units.
10. OHM law: equation and application example.
11. Differences between direct and alternating current.
12. Answer the following questions:
a) How many millivolts are 20V?
b) How many milliamps are 2.3 to?
c) How many kilovolts are 1.245V?
d) How many amps are 1.3 kA?
e) How many ohms is 2.5 milliohms?
13. If a 100Ω resistor will connect a 12.5 V battery, how many amperes
pass through the resistance?.
14. If now we change the battery, so the resistance 10A pass, how many volts will the new battery?.
15. Imagine now that this new battery has a resistance of
connect so that she spends 2A, of what value we will post the new
Resistance?.
