## Why capacitor is connected in parallel rectifier?

When you have more than one capacitor in parallel, they have the same voltage (because they are in parallel), and each stores a certain charge. The total charge (at a given voltage) will be the sum of the charges on all the capacitors.

## What is the purpose of the capacitor that is placed in parallel to the load in a half wave or full wave rectifier?

Smoothing capacitors are connected in parallel with the load across the output of the full wave bridge rectifier. This filter circuit increases the average DC output level as the capacitor acts like a storage device. The smoothing capacitor converts the rippled output of the rectifier into a smoother DC output.

## What is the effect of adding capacitor in parallel to the load at the rectifier output?

Voltage ripple can be smoothed by adding parallel capacitors across the load in a rectifier circuit. The degree of smoothness increases when the capacitance increases.

## Why capacitor is used in parallel?

(a) Capacitors in parallel. Each is connected directly to the voltage source just as if it were all alone, and so the total capacitance in parallel is just the sum of the individual capacitances. (b) The equivalent capacitor has a larger plate area and can therefore hold more charge than the individual capacitors.

## Why capacitor is connected parallel with inductive load?

With the capacitor in parallel, there is now an additional source of energy, which can take up some/all of the burden of supplying current to the inductive load (when it resists changes in current till it sets up its field), after which the source takes over again and recharges the capacitor.

## Why load is connected in parallel?

In the parallel system, each of the load elements is connected across the same terminals, therefore each has the same voltage drop: … Voltage across each resistor is the same as the voltage across the parallel combination.

## What purpose does a capacitor serve when placed in parallel with the load resistor at the output of a full wave bridge rectifier?

Capacitors are used to smooth out or filter the ripple present in the rectified DC, and sometimes more complex filters using inductors as well as capacitors are used.

## Which of the following is the primary reason for connecting capacitor in parallel in the rectifier circuit?

Smoothing or reservoir capacitors connected in parallel with the load across the output of the full wave bridge rectifier circuit increases the average DC output level even higher as the capacitor acts like a storage device as shown below.

## What is the effect of adding the capacitor across the load?

Voltage ripple can be smoothed by adding parallel capacitors across the load in a rectifier circuit. The degree of smoothness increases when the capacitance increases.

## What will be the effect of a capacitor connected in parallel with the load on the output of the bridge rectifier?

Well, the capacitor that is connected parallel to the load resistance is used to smoothen the signal we get from the rectifier circuit. While converting AC to DC, we use therectifier circuit but the circuit does not completely convert the AC signal to DC signal. Hope it helps you.

## What does V ripple represent?

Ripple voltage means the amount of AC voltage that appears on a DC voltage. The main reason for the ripple voltage is that the converter converts the AC voltage into a DC voltage, but the AC voltage cannot completely eliminate.
