Abstract

The invention discloses a forward and backward volt-ampere characteristic measuring device for a diode. The device includes a power source, a single-pole single-throw switch, a slide rheostat, a resistance box, a milliammeter, a voltage meter and a diode. The device also includes a first single-pole double-throw switch, a second single-pole double-throw switch, a third single-pole double-throw switch, a fourth single-pole double-throw switch. According to the invention, switching between a forward volt-ampere characteristic measuring and a backward volt-ampere characteristic measuring circuitcan be realized conveniently without circuit disassembly, wiring error rate can be reduced and improvement of experiment efficiency can be facilitated.

Description

technical field [0001] The invention relates to an experimental device for measuring resistance, in particular to a device for measuring forward and reverse volt-ampere characteristics of a diode. Background technique [0002] The measurement of diode volt-ampere characteristics is a basic electrical experiment. Due to the great difference between the forward and reverse volt-ampere characteristics of diodes, different circuits are required for measurement. After measuring the forward volt-ampere characteristics, the original circuit must be disassembled, and another circuit must be rebuilt to measure the reverse volt-ampere characteristics, and vice versa, which brings inconvenience to the experimenter and easily increases the wiring error rate. Even cause damage to diodes and ammeters. Contents of the invention [0003] The purpose of the present invention is to develop a diode forward and reverse volt-ampere characteristic measuring device which is convenient for exper...
