EXERCISES



EXERCISE 9 SHEET

       CIRCUITO 1









In order that the bulb is ignited is necessary to activate I1 and I2 .
     CIRCUITO 2



In order that the bulb is ignited we have to activate I1.
    
 CIRCUITO 3



In order that the bulb is ignited we have to activate I1 or I2 or you can activate both at the same time.
     CIRCUITO 4



In order that the bulb is ignited we have to activate I1 and push P1.
     
        CIRCUITO 5



In order that the bulb is ignited we have to activate I1 and I2.






        CIRCUITO 6


In order that the bulb is ignited we have to activate only I1 beacuse if we activate I2 there is short-circuit. 




     CIRCUITO 7



In order that the bulb is ignited we have to activate I1 and I2.



    CIRCUITO 8



In order that the bulb is ignited we have to push P2.




 CIRCUITO 9


In order that the bulb is ignited we have to activate I1 and I2.

    CIRCUITO 10



In order that the bulb is ignited is necessary to activate  I1 and I2.







EXERCISE 10 SHEET

Apartado a)

It's a circuit with two bulbs and a NA  push button. We need to push it so the bulbs will be on





Apartado b)


It's a circuit with a switch and a switcher that changes between a motor and a buzzer. 





Apartado c)


It is a circuit with two NA push buttons but one turns a bulb on and the other makes a motor turn around.





Apartado d)



It's a circuit with a NC push button and three bulbs that are on but without many energy.



EXERCISE 31 SHEET


 a)How many tension will give the generator?

  • It will give 9 volts
 b)How many tension will use bulb 1?
  • It will use 4.5 volts.
 c)How many tension will use bulb 2?
  • It will use 4.5 volts
 d)How many current intensity will run in the circuit?

  • It will run 45 mA.



EXERCISE 47 SHEET


 a)What happens if we don't push the pusher and we don't activate the switch?
  • The motor is stopped.

 b)What happens if we activate the switch but we don't push the pusher?

  • The motor turns to the left (like in the image).

 c)What happens if we push the pusher and we activate the switch?

  • The motor will turn to the right.

 d)What happens if we stop pushing the pusher?

  • The motor will turn again to the left like in the image.

 e)What is the use of this system?

  • I think it is used for changing the sense of the motor.
