have :
(a) low. ripple factor and low
voltage regulation
(b) high ripple factor and low
voltage regulation
(c) low ripple factor and high,
voltage regulation
(d) high ripple factor and high
voltage regulation​

Answer 1

Answer:

Option (a)

Explanation:

A good power supply should have low ripple factor and low voltage regulation

Ripple factor;

It is the variation in DC voltage after rectification from AC to DC. To reduce, this we use filters. It is best to reduce it to minimum level.

Voltage regulation;

It is the variation in the output voltage. Normally it is best to operate equipment at fixed voltages. It is also safe for the equipment
