Abstract
The utility model discloses an experimental device for the inhibition of inductance and capacitance to alternating current. The experimental device related to the technical field of physics teaching aids. A wiring terminal, a single-pole switch 1 and a small bulb are electrically connected with another wiring terminal through a lead wire. A single-pole switch 2 is connected with a 200 Mu F capacitor in series and then is connected with the single-pole switch 1 in parallel; a single-pole switch 3 is connected with a 470 Mu F capacitor in series and then is connected with the single-pole switch 1 in parallel; a single-pole switch 4 and a high-frequency choke coil are connected in series and then are connected on the single-pole switch 1 in parallel; and a single-pole switch 5 is connected and a low-frequency yoke coil are connected in series and then are connected on the single-pole switch 1. Compared with the prior art, the inhibition of the inductance and the capacitance to the alternating current can be compared and shown on the same demonstrator so as to be intuitive and convenient. So the experimental device is the physics tooling aid which is convenient to improve and popularize.
Description
Technical field
The utility model relates to a kind of physical teaching aid, is a kind of inductance and the electric capacity inhibition tester to exchange current specifically.
Background technology
Teaching edition senior middle school newly to levy mark physics the people takes as an elective course in the teaching among the 3-2, " inductance and electric capacity are to the influence of exchange current " is a difficult point, do you how to understand this knowledge point? do not have ready-made teaching aid in the teaching material, be unfavorable for the student to this part knowledge produce intuitively, the understanding of perception.
The utility model content
The purpose of this utility model is the deficiency that lacks relevant teaching aid at existing teaching material, and a kind of inductance and the electric capacity inhibition tester to exchange current is provided.
The purpose of this utility model realizes by following technological means: inductance and electric capacity are to the inhibition tester of exchange current, and binding post one, single-pole switch one, miniature bulb and binding post two are electrically connected by the lead order.
Described inductance and electric capacity is to the inhibition tester of exchange current, is parallel on the single-pole switch one after also comprising the capacitors in series of single-pole switch two and 200 μ F again; Be parallel on the single-pole switch one after the capacitors in series of single-pole switch three and 470 μ F again; Be parallel to again on the single-pole switch one after single-pole switch four and the high frequency choke coil series connection; Be parallel to again on the single-pole switch one after single-pole switch five and the low-frequency choke coil series connection.
Described inductance and electric capacity are above-mentioned two cover contrast circuit to the inhibition tester of exchange current.
Compared with prior art the utlity model has following tangible advantage: inductance and electric capacity can be contrasted displaying to the inhibition of exchange current on same demonstration device, directly perceived, convenient, be a kind of physical teaching aid of improving and promoting be convenient to.
