- List three types of capacitor.
- In figure 1, calculate the total:
(i) capacitance;
(ii) charge;
(iii)voltage across capacitor C2.
The expected answers were:
(a) Types of capacitor
(i) Paper capacitor
(ii) Fixed capacitor/Variable capacitor
(iii) Polarized/non-polarized capacitor
(iv) Mica capacitor
(v) Ceramic capacitor
(vi) Electrolytic capacitor
(vii) Air capacitor
(viii) Tantalum capacitor
(b) (i) CT = = = 2.4 µF
(ii) QT = CTVT = 2.4 x 10-6 x 12 = 28.8 x 10-6 C.
(iii) VC2 = = = 7.2 V
