Part 2
3. What is the difference between half-wave and full-wave rectifiers.
Our purpose is to change an AC signal to DC signal as shown in Figure 1a. There are
two ways to achieve our purpose: half-wave rectification and full-wave rectification as
shown in Figure 1b. The rectifiers are sketched in Figure 2 and 3 respectively.

Procedure
1. Half-wave rectification
Keeping the capacitor as 10µF, measure the ratio V1/Vo and record into Table I
2. Full-wave rectification
Keeping the capacitor as 10µF, measure the ratio V1/Vo and record into Table II
