A capacitor is used a) to supply voltage.b) to increase the voltage output.c) to store energy.2. The main parts of a capacitor are a) insulators only.b) metal plates only.c) metal plates and insulators betweenthem.3. The function of insulators is4. The capacity of a capacitor dependson5. The capacity of a fixed capacitor6. The plates of a variable capacitor7. In order to charge a capacitor avoltage source is applied8. The greater the distance betweenthe plates,-S Sa) to store energy.b) to isolate the metal plates.c) to prevent a short between themetal plates.a) the size of the plates.b) the distance between the plates.c) the material of the insulators.a) is constant.b) is varied.a) can be moved.b) cannot be moved.a) to the metal plates.b) to the insulators.a) the greater is the capacity of acapacitor.b) the less is the capacity.9.
