Q What Are Microwaves? Ans Microwaves Are Very High Frequency Waves  That Operate at 2450 Mhz. At frequencies of 2.45 Ghz, MWs are absorbed by water, sugar and fat  molecules and converted into atomic motion. At these frequencies, MW are not absorbed by plastics, ceramics etc. and reflected by metals Q How Do Microwaves cook ? 1) In a Microwave oven, a Magnetron tube emits the MWs. 2) These Microwaves pass through the food. 3) The water molecules in the food begin to oscillate. 4)The oscillation generates heat energy due to friction. 5) The heat generated hence cooks the food particles nearby. Comparision Conventional Gas Vs Microwave Owen CONVENTIONAL GAS 1) Layer-by-layer, Outside to inside. 2) Spoils the kitchen wall with sprinkling of oil. 3) Separate utensils for cooking & serving. 4) More usage of Oil/Ghee. 5) More time consuming & tiring. 6) Nutritional Value of the food is lost due to longer cooking. 7) Installation Cost Is low B

Watt’s Law According to the Watt’s Law the total power of the circuit is equal to the product of the current and voltage of the circuit. By using this formula you can even calculate the voltage and current if you have the other two values. The formulas follow the Watts’s law triangle,                       P= VI Where, P represent Power, V represents Voltage and I represents Current. Power (P) = Voltage (V) x Current (I) Voltage (V) = Power (P) ÷ Current (I) Current (I) = Power (P) ÷ Voltage (V) As, we know this calculator calculates the Power in Watts using the current and voltage value. What if you don’t have one of them or you have the resistance value of the circuit. For theoretical calculation you can use the below mentioned formulas: Power = (Voltage) 2 ÷ Resistance Power = (Current) 2 x Resistance

1) CURRENT = CURRENT IS NOTHING BUT THE FLOW OF FREE ELECTRON IN THE CIRCUIT IN THE CLOSED PATH. THE UNIT OF CURRENT IS MILLI AMPERE AND AMPERE AND IS DENOTED BY CAPITAL I. 2) VOLTAGE = Voltage is what makes electric charges move. It is the 'push' that causes charges to move in a wire or other electrical conductor. It can be thought of as the force that pushes the charges, but it is not a force. Voltage can cause charges to move, and since moving charges is a current, voltage can cause a current. generally measure by voltmeter and denoted by capital V. There are two types of voltage, DC voltage and ACvoltage. The DC voltage (direct current voltage) always has the same polarity (positive or negative), such as in a battery. The AC voltage (alternating current voltage) alternates between positive and negative. For example, the voltage from the wall socket changes polarity 60 times per second (in America). The DC is typically used for electronics and the AC for motors.

किसी भी चिकित्सा सहायता के आने से पहले किसी दुर्घटना या अचानक बीमारी के शिकार व्यक्ति को दिया जाने वाला तात्कालिक उपचार "प्राथमिक चिकित्सा उपचार" कहलाता है प्राथमिक चिकित्सा किट को सभी प्रकार की चोटों का प्रबंधन करने के लिए डिज़ाइन किया गया है, जिसमें मूल कटौती, स्क्रैप और जलता है। छोटी चोटें बड़ी चोटें बन सकती हैं - जितनी अधिक देर तक आप उपचार की प्रतीक्षा करेंगे, आपकी चोट उतनी ही अधिक गंभीर हो सकती है। तत्काल उपचार से जोखिम को कम किया जा सकता है। पीड़ित को जीवित रखें। पीड़ित की स्थिति को बिगड़ने से रोकें। सहायता आने तक प्राथमिक उपचार दें। सुनिश्चित करें कि पीड़ित को आवश्यक चिकित्सा देखभाल प्राप्त हो। घटक ओएफ फर्स्ट एड। 1) डेटॉल साबुन = पानी का उपयोग सतही घावों को साफ करने के लिए पानी के साथ किया जाता है 2) बैंड-ऐड्स = एक बैंडेज एक ऐसी सामग्री का एक टुकड़ा है जिसका इस्तेमाल या तो किसी चिकित्सा उपकरण जैसे कि ड्रेसिंग या स्प्लिंट का समर्थन करने के लिए किया जाता है, या शरीर के एक हिस्से की गति को सीमित करने के लिए समर्थन प्रदान करने के लिए किया जाता है। ... तंग पट्टियों

                     MIXER GRIENDER Mixer Griender Working = A  mixer grinder  is essentially a  mixer  with a  grinder  combined. They are used to do things like  mixing , blending and  grinding  of different food ingredients.  Mixer grinder  comes with at least two different jars - one used for wet sauces and another for making dry powders. PARTS USED IN MIXER. 1) MOTOR= The universal motor is a type of electric motor that can operate on either AC or DC power and uses an electromagnet as its stator to create its magnetic field. It is a commutated series-wound motor where the stator's field coils are connected in series with the rotor windings through a commutator. 2 ) ROTARY SWITCH = Rotary switches move in a circle and can stop in several positions. They are used to control many different circuits with a single switch. ... The rotors are on a spindle and each rotor has an arm projecting outward that can make contact with a terminal when the switch is in a certain
