# Electricity:

1. What is the electrical current. Types. He defines the classes of current with the help of a drawing
2. Magnitudes of the current and law that relates them
3. That functions has within the alternator the exhaust fan?
4. The instrument that is used to measure the electrical magnitudes is called.
5. Power. It defines what is and formula
6. Circuit series. drawing and explains that it is fulfilled
7. Circuit in parallel. That is fulfilled in this type of circuits?
8. Differences between pulser, commutator and switch. Two examples of each
9. How the sense of a motor with a commutator changes
10. It explains as a relay works
11. It realises all the activities of the book and exercises of page 94 and 95
12.  In a house we have connected to 220 V the following electric home appliances) a washing machine with a total resistance of 22 Ohmiosb) a refrigerator with R = 200 Ohmiosc) a television with R = 220 Ohms

To realise the electrical circuit, to calculate the resistance equivalent and the provided current to the house

13.  In the following circuits, to calculate the equivalent resistance and the Current intensity that leaves the battery    The following exercises are only for the students of 3 THAT
14. Two light bulbs in series of 10 Î© are connected with two in parallel of 40 Î©. If the tension of the battery is 100 volts, to calculate the current of the battery and the tension that falls in one of the resistance of 10 Î©. It draws the circuit
15. Two light bulbs in series of 100 Î© are connected with two in parallel of 40 Î©. If the tension of the battery is 100 volts, to calculate the power that there is in one of the ressitencias of 100Î©. It draws the circuit
16. We have connected a TV of 220 200 volts consuming mA. If the Kwh costs 20 pennies, it calculates the monthly cost if it is connected 10 hours to the day (month of 30 days)
17. In the circuit of the figure, to calculate the current that leaves the battery. 18. To calculate the tension that there is in the R1 resistance. 19. In the circuit of the figure, to calculate the tension that there is in the resistance of 400 Ohms Schemes realised with the program Oregano in platform linex

Energy

1. As the energy is moderate. Units
