CAIE A-Level Physics A2 21.2.3 The Use of Four Diodes Bridge Rectifier for the Full Wave Rectification of Topic Practice

CourseCourseConceptConcept

Question 1

[Maximum number: 4]

Four diodes are used in a bridge rectifier circuit to produce rectification of a sinusoidal a.c. input voltage VIN V_{\text {IN }}.
Fig. 7.1 shows part of the circuit, but three of the diodes are missing.
