54(a) Define the capacitance of a capacitor
(b) State:
three factors on which the capacitance of
a parallel plate capacitor depends.
(ii) two uses of capacitors.
(c) The plates of a parallel - plate capacitor
are 5mm apart and 2m² in area. The places
are in vacuum. A potential difference of 1k
is applied across the capacitor.
Calculate the:
(i)
Capacitance
ii) charge on each plate
iii) electric intensity in the space between them
iv) energy stored in the capacitor
