Just consider variables that you can change up, like materials or other parameters. Many of these science experiments for high school are intended for classroom labs, but most can be adapted to become science fair projects too. ![]() Other projects involve fire, chemicals, or other materials they couldn’t use before. Some science experiments for high school are just advanced versions of simpler projects they did when they were younger, with detailed calculations or fewer instructions. What are the factors to be considered when you select a bulb?Įfficiency, energy consumption, low energy loss, less environmental pollution.The cool thing about high school science experiments and projects is that kids are old enough to tackle some pretty amazing concepts. Loss of electricity in the form of heat is less, more life span, no shadow formation, more light is obtained, less consumption of electricity. What are the advantages of using discharge lamps instead of incandescent lamps? What are the other types of lamps working on electricity? List them. It can remain only in red hot condition but it can’t give light.Ī filament lamp is lit for a short period of time. Nichrome is not used as filament in incandescent lamps. Ability to emit white light in the white-hot conditions.What are the advantages of using tungsten as a filament? Why is the bulb filled with an inert gas or nitrogen? When the tungsten comes in contact with the air in the heated condition The interior of the bulb is evacuated to pr-event the oxidation of filament. What happens if the interior of the bulb is not evacuated? H = 2400 J = \(\frac\) = VIĪ current of 0.4 A flows through an electric bulb working at 230 V. If 4.2 J is one calorie then H = ……… calorie → What was the change that happened to the temperature of water in both the beakers on increasing the time? → What change is observed in the temperature of water in both the beakers when the current is increased using the rheostat?Īs the current increases, the heat produced is increases. Since nichrome has high resistance, more heat is produced. → Of the water in beakers A and B which one got heated more? Why? (Page no.11).Īnalyse the table and find out the factor that influences heat the most. Then, the charge that flows through the conductor in t second,įactors influencing the heat developed when a current passes through a conductor.Ĭomplete the following table on the basis of Joule’s Law. If the ammeter shows a current I ampere on applying a potential difference V across the resistor of resistance R Ω Lighting Effect of Electric Current Question 5. It can only be converted from one form to another (Law of Conservation of Energy) As the resistance of Ni-chrome is higher it produced more heat. This based on the concept that energy can neither be created nor destroyed. → In this case which form of energy was converted into heat energy? → How does the ni-chrome wire become red hot while passing electricity through the circuit? ![]() Heat Chapter Class 10 Questions and Answers Question 4. Which are the devices that give heating effect of electric current? Heating Effect of Electric Current Class 10 Question 3. Write down the energy changes in them with respect to their use. Some electrical devices are shown in the house of the child.
