wireless current transmission

The presented circuit works to transfer electricity from one place to another without wires.  In this project there are two coils made of copper wire, one coil acts as transmitter and the other coil acts as receiver.  This is a very efficient structure used for magnetic induction.

The circuit diagram of wireless current transmission is given below. In It uses a coil made from 100 turns of copper wire on a PVC pipe and a transistor BD139 is also used in this circuit.  

Pin 1 of the coil used in the transmitter circuit is connected to the base of the transistor BD139 through a 10K ohm resistor and pin 3 of the coil is connected to the collector of the transistor.  Pin 2 of the coil (which happens after 50 turns) is connected to +9v.

This wireless current transmission circuit converts DC current into high frequency AC current and generates a magnetic field around.  

wireless current receiver 
When the receiver coil is placed in a magnetic field, current is generated in it and the LED connected to the receiver coil starts flashing as shown in the figure below.  

In the below circuit diagram, both the transmitter and receiver coils are shown together.

पानी की टंकी मोटर स्वचालित चालू / बंद स्विच  प्रस्तुत सर्किट द्वारा पानी की टंकी पूरी तरह से भर जाने के बाद टैंक की मोटर अपने आप बंद हो जाती है। और टंकी में पानी खाली होने पर मोटर अपने आप चलने लगती है।  इस परिपथ में IC 555 का प्रयोग किया जाता है। IC 555 इस सर्किट और टाइमर सर्किट दोनों में समान रूप से काम करता है। और IC सुरक्षा के लिए, हमने इसमें एक डायोड in4007 जोड़ा है। इसके अलावा इस सर्किट में 2 ट्रांजिस्टर BC548 का भी इस्तेमाल किया गया है। और एक रिले 18V का उपयोग ऑन-ऑफ स्विच के रूप में किया गया है। इस परियोजना में हमें तीन तारों को पानी की टंकी में विसर्जित करने की आवश्यकता है। +V तार को पानी की टंकी के सबसे निचले स्तर पर रखा जाना चाहिए और ic के ट्रिगर पिन 2 वाले तार को पानी की टंकी के मध्य स्तर पर रखा जाना चाहिए। और तीसरा तार जो ट्रांजिस्टर Q1 के आधार से जुड़ा है, पानी की टंकी के शीर्ष पर रखा गया है। काम करने का ढंग पानी की टंकी मोटर ऑटो चालू/बंद स्विच
