What is a potential divider used for?
What is a potential divider used for? A potential divider is a simple circuit that uses resisters(or thermistors / LDR’s) to supply a variable potential difference. They can be used as audio volume controls, to control the temperature in a freezer or monitor changes in light in a room. Why do we need voltage? Electrical […]

What is the full form of LCD? A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Who invented logo? Wally Feurzeig Who logo means? WHO’s emblem was chosen by the First World Health Assembly in 1948. The emblem consists […]
When atoms are bombarded with alpha particles only a few in million suffer deflection others pass out Undeflected This is because?
When atoms are bombarded with alpha particles only a few in million suffer deflection others pass out Undeflected This is because? When atoms are bombarded with alpha particles, only a few in millon suffer deflection, other pass out undeflected. This is because. The nucleus occupies much smaller volume compared to the volume of the atom. […]
What is the ratio of molecules in 1 mole?
What is the ratio of molecules in 1 mole? 1 mole of any compound is the Avogadro’s number, 6.023×1023 . And, 1 mole of HNO3 = 6.023×1023 molecules. Now, both compounds have the same number of molecules. The ratio of molecules between both the compounds is 1:1 . Which is the correct formula to calculate […]

Can the amount the balloon fills up be controlled by the amount of vinegar or baking soda?
What is better a generator or inverter?
What is better a generator or inverter? Conventional portable generators are able to produce more power than inverter generators. This has to do with a number of factors including the size of the fuel tank and the mechanical difference in electricity production. Inverter generators are more energy efficient thanks to how the final AC current […]
