10. Draw the following circuits:
a. Circuit with a 9-volt battery, a PTM push switch and two bulbs that shine at the same time when you push
the switch.
b. Circuit with a 9-volt battery, a general switch to turn everything on/off and a double throw switch to
select what is working: a motor or a buzzer
c. Circuit with a 6-volt battery and two PTM push switches, one of them used to turn on a bulb when you
push it, and the other to turn a motor on when you push it.
d. Circuit with a 9-volt battery, a PTB push switch and three bulbs that are switched off at the same time
when you push the switch.

11.  A short circuit is an accidental connection between the two terminals of an element. In the following circuit there is a shortcut in one of the bulbs. 

a.  Explain  what  will  happen  in  the  circuit  when  the  switch  is turned on.

 The first bulb doesn´t light because there is another path with no resistance where the current flows.

b.  What  would  happen  in  the  circuit  if  the  short  circuit  is eliminated?

Both bulb light, but get dimmer as there is more resistance in the circuit.

12.  Using a battery, a PTM push switch, a standard switch, a buzzer and a bulb, draw a circuit in which the buzzer sounds if we push the PTM push switch and the standard switch turns the bulb on/off. 

13.  Using a battery, a PTM push switch, a double throw switch, a motor and a bulb, draw a circuit in which the motor will work in one of the positions of the double throw switch, and in the other position the bulb will light if the push switch is also pushed. 

16.  Using a battery and three bulbs, draw a series circuit and a parallel circuit, and answer the following questions: 

a.   How can we know that a circuit is series or parallel?

Series: The current that flows across each component is the same and the voltage of the supply is shared between the components.

Parallel: The voltage across each component is the same and the current is shared between each component.
  

 

b.   What happens in each of them if one of the bulbs blows out? Why?

Series: the others bulbs will not light because the circuit will be opened.

Parallel: the others bulbs will light because both paths are closed.

c.   Adding a switch to the circuits, can we switch only one of the bulbs on/off in each of the two
circuits? Why?

Series: no, because in a series circuit we have only one path to let current flows.

Parallel: yes, because in a parallel circuit we have independent paths to let current flows.

d.   In which one the circuits will the bulbs light brighter? Why?

In the parallel circuit because all the bulbs have the same voltage: 9V and in the case of the series circuit the bulbs have to share the voltage.

INTERLOCKED (VIDEOGAME): TRAIN YOUR SPATIAL VIEW!

Wrap your mind around the next intensive puzzle game - Interlocked!

A 3D puzzle game with a chilling atmosphere.

You know those puzzles consisting of a few wooden blocks that are impossible take apart? Then you know Interlocked. Each level, you’re given a unique 3D puzzle consisting of blocks that hold each other together. Take it apart and you'll feel ten times as smart :-)

Use the Glance Tool, looks like an eye, to rotate the puzzle with the mouse. Use the Pull Tool, looks like a hand, to click and drag on a piece to pull in the desired direction. You may switch between the modes using spacebar.

YOUR MARKS!

Aquí tenéis las notas de vuestro primer examen. Recordad que estaba dividido en dos partes, una relacionada con el dibujo y otra con el Proceso Tecnológico. Es posible que tengáis una parte aprobada y la otra no. En ese caso, en el examen de recuperación os examinaríais solo de la parte no superada.

Enhorabuena a los que habéis aprobado y ánimo a los que no hayáis superado esta prueba. Tendréis una oportunidad más de superarlo en un examen de recuperación que haremos en la primera semana de diciembre, junto con un examen que contendrá problemas de la ley de la palanca (incluyendo las poleas y tornos) y tipos de palanca. Espero que estéis haciendo los problemas que os dejé de tarea y que estéis trabajando el vocabulario de las fotocopias que os entregué.

Views: solutions

Here you have the solutions for the pieces I´ve given to you. Try to check if you have done right. And you know, if you have some doubts, you can ask me.

Remember:

Related to the distribution:

• The front is usually indicated with an arrow 
• The views distribution:
• The front is always on top of the floor
• The profile is situated the other way around, that is, the left profile is situated on the right

Related to the dimensions:

• The same height: the object has the same height on the floor and on the profile views 
• The same width: on the front and on the floor views 
• The same depth: on the floor and on the profile views
