register is an electrical component used to reduce the electrical
current in a circuit. The register is measured in units of ohms and has two
terminals.
The register is constructed using carbon or metal wire. There are mainly two
types of registers, fixed value registers, variable registers.
Fixed value resistors,
The value of fixed value register is always fixed, its value cannot be
increased or decreased whereas the value of variable register can be increased
or decreased.

Select the colors of the bands on your resistor:
The value of the fixed value register is indicated above it in the form of a
color band. It is made of electro-resistant material. Fixed value registers
also belong to the following categories.
Flameproof Mattel oxide resistors,
Flameproof Mattel oxide resistors is produced by coating a thin layer of tin
chloride on a glass rod which is shown in the picture below.
Carbon film resistors,
Carbon Film Register is manufactured from high grade ceramic material.
Which is shown in the picture below.
Wirewound resistors;
Wirewound resistors are manufactured by winding tungsten, nichrome or nickel
wire over an insulator rod. The value of this resistor depends on the length
of the wire.
Variable resistors;
The value of the variable resistor is not always fixed, its value can be
increased or decreased as per the requirement. Variable resistor is
used to increase or decrease the volume in radio, TV and music system etc.
It is of three types.
Potentiometer variable resistors
The potentiometer variable resistor shown in the following figure is used to
control the voltage level in any electrical circuit. By rotating the
knob in it, you can set it to the value as per the requirement.
trimmer or preset is a variable resistor that is embedded in a PCB board
along with other components and requires a screwdriver to change its value.
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
