- 13. Multiple ChoiceHow does this circuit work?When push the switch the transistor changes the position of the 2 ways switch and the led shinesWhen push the 2 ways switch the led shines thanks to the capacitorWhen push the switchthe relay changes the position of the 2 ways switch and the led shinesWhen push the switch the led shines because the transistor amplifies the current
- 14. Multiple ChoiceA example of this circuit is...A heating: when the temperature is low the motor worksA fan: When the temperature is high the motor worksA sensor: show the temperature of the motorAn alarm: If the temperature of the motor is high the alarm rings
- 15. Multiple ChoiceHow does this circuit work?When the LDR receives light the relay changes and the led shinesWhen the LDR doesn´t receive light the relay change and the led turns offWhen the LDR generates light the led shinesWhen the LDR generates light the led turns off
