Air dielectric capacitors are used mainly as laboratory standards of capacitance for measurement purposes. The insulating material used in these capacitances is fused silica and the whole capacitor is shielded in the metal case. They are very accurate (0.01 to 0.02%) but their size is large. The construction is parallel plate or concentric cylinder type. Plates are circular, square or triangular in shape. These metallic plates are insulated from each other and separated by air.
Specifications
Range of values 50pf to 10000pf
Tolerance 0.01 to 0.05%
Temperature coefficient 10ppm/0C
Applications: As residual inductance and resistance is low, they can be used at high radio frequencies. Also can be used a high voltage laboratory standards.
The current in an RL circuit builds up one-third of its steady value in 4.56s. Find the inductive time constant.
In this type of capacitors the dielectric consists of an extremely thin film of aluminium oxide formed on one of its aluminium foil plates. Intimate contact with the other plates i
FACTORS AFFECTING INDUCED EMF By experiment, the following factors may be noted: • The faster the magnet (or coil) is moved, the greater is the deflection obtained on the meter
