1. List three types of capacitor.

1. 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
