Abstract
The invention provides an inductor and capacitor alternating current experiment device, which comprises a display plate, wherein an inductor, a capacitor, a resistor, a power supply switch, a double-pole double-throw switch and a loudspeaker are respectively arranged on the display plate, and the inductor, the capacitor and the resistor are respectively connected with bulbs. The inductor and capacitor alternating current experiment device has the advantages that the structure is simple, the use is convenient, the operation is simple, the demonstration effect is good, the time is saved, and the like.
Description
Technical field
The present invention relates to teaching aid, the experimental provision of especially a kind of inductance and electric capacity exchange current.
Background technology
Teacher is in teaching " inductance and electric capacity are on the impact of exchange current " this class, general teacher will do two experiments, experiment is together in series with miniature bulb respectively at the coil of ribbon core (inductor) and capacitor, receive respectively again in direct supply and AC power, and the effective value requiring the voltage of direct supply and alternating voltage equally, finally observes the brightness of bulb.But two experiments use equipment more, and repetitive operation is many, expends time in many, inductance and electric capacity affect an experiment one first rear demonstration to exchange current, comparative strong, and be unfavorable for repeatedly demonstrating, wherein and have experiment to make an explanation on the impact of alternating current frequency size on induction reactance and capacitive reactance.
Summary of the invention
Object of the present invention is improved above shortcoming exactly, provides structure simple, easy to use, improves the inductance of demonstrating effect and the experimental provision of electric capacity exchange current.
Concrete scheme of the present invention is: the experimental provision of inductance and electric capacity exchange current, it is characterized in that: there is Graphic Panel, Graphic Panel is furnished with inductor, capacitor, resistance, power switch, double-point double-throw switch and loudspeaker respectively, and inductor, capacitor and resistance are all connected with bulb.
Structure of the present invention is simple, easy to use, simple to operate, good demonstration effect, and the advantage such as save time.
Fig. 1 is structural representation of the present invention.
Fig. 2 is circuit diagram of the present invention.
In figure, 1-Graphic Panel, 2-inductor, 3-capacitor, 4-resistance, 5-power switch, 6-double-point double-throw switch, 7-loudspeaker, 8-bulb.
Embodiment
See Fig. 1-2, the experimental provision of inductance of the present invention and electric capacity exchange current, have Graphic Panel 1, Graphic Panel 1 is furnished with respectively inductor 2, capacitor 3, resistance 4, power switch 5, double-point double-throw switch 6 and loudspeaker 7, inductor, capacitor and resistance are all connected with bulb 8, during demonstration, power switch is opened, switch on power, double-point double-throw switch is allocated to zero frequency span place, the bulb be connected with inductor and the bulb luminescence be connected with resistance can be found, and the bulb that electric capacity is connected is not bright, double-point double-throw switch is allocated to and exchanges shelves stream shelves place, ac frequency is transferred to minimum, loudspeaker sound is minimum, the bulb be connected with inductor and the bulb luminescence be connected with resistance can be found, the bulb be connected with capacitor does not work, when gradually ac frequency being heightened, the sound of loudspeaker becomes large gradually, can find that the bulb be connected with inductor is dimmed to extinguishing gradually, the bulb be connected with capacitor brightens gradually, the bulb brightness be connected with resistance is constant, can be reached a conclusion by above phenomenon, inductor leads to direct current, and resistance exchanges, logical low frequency, resistance high frequency, capacitor is logical to be exchanged, resistance direct current, logical high frequency, resistance low frequency.
Claims (1)
1. the experimental provision of inductance and electric capacity exchange current, is characterized in that: have Graphic Panel, and Graphic Panel is furnished with inductor, capacitor, resistance, power switch, double-point double-throw switch and loudspeaker respectively, and inductor, capacitor and resistance are all connected with bulb.
