Technology 4 ESO – Unit 2 ELECTRONICS page 20 activity 12
a) Watch the video on “Capacitors Explained” and answer:
- I) Why we shouldn’t touch the terminals of a capacitor?
- II) What are the two differences between a capacitor and a battery?
- III) What is the function of a capacitor in a circuit?
- IV) How do we know what side of a capacitor is the negative side?
- V) When does the capacitor provide power?
- VI) What two values we find on the side of the capacitor?
- VII) In what unit do we normally measure capacitance?
- VIII) What can make a capacitor explode?
- IX) What is the function of the capacitor when we use a “full bridge rectifier” to convert AC to DC power?
- X) To check the voltage, how do we connect a multimeter to a capacitor?
b) In this link http://www.wikihow.com/Read-Capacitor we can learn how to read capacitors.
Then read the value of these three capacitors:
