演示电感和电容对交变电流影响的装置

Demonstrator of the effects of inductance and capacitance on alternating current

将电源、电容、电感、电阻及小灯泡安装在电路演示板上,连接不同的电路,通过灯泡的明暗,可以分别直观地展示出电感和电容对交变电流的影响,同时也可以探究影响电感感抗大小的因素.

A circuit with power source ,capacitance ,inductance ,resistance and bulb was de‐signed .After connecting different circuit ,by judging the brightness of the bulb ,the effects of induct‐ance and capacitance on alternating current were obviously shown .Using this demonstrator ,the influ‐ence factors on inductive reactance were explored .
