Q1:

An inductor filter has a ripple that __________ with load resistance and consequently is used only with relatively __________ load currents.

A decreases, low

B decreases, high

C increases, low

D increases, high

ANS:D - increases, high

In inductor, ripple decrease with load resistance.

So, if load resistance increase, load current decrease and therefore ripple will increase.
