Which is the best example of potential energy? Potential energy is the stored energy an object has because of its position or state. A bicycle on top of a hill, a book held over your head, and a stretched spring all have potential energy. What are two examples of kinetic and potential energy? What Are […]

Why electrical appliances are not connected in series?
Why electrical appliances are not connected in series? Answer. Electrical appliances are not connected in series because current will be same through all the appliances connected whereas appliances have different current ratings and also that voltage decreases as more no. Of appliances are connected. What happens if the household electric appliances are connected in series? […]

How high can a helium balloon go?
How high can a helium balloon go? 9,000 meters What happens to a helium balloon in space? One is that atmospheric pressure is dramatically reduced at high altitudes, so a helium balloon expands as it rises and eventually explodes. But the elasticity of rubber decreases at very low temperatures so it is possible that helium […]
Can a load be a resistor?
Can a load be a resistor? Devices called resistors are built to provide precise amounts of resistance in electric circuits. Any device that performs some useful task with electric power is generally known as a load. Sometimes resistor symbols are used in schematic diagrams to designate a non-specific load, rather than an actual resistor. What […]
Is a double bond one electron group?
Is a double bond one electron group? Double or triple bonds count as a single electron group. The molecule will not be a perfect equilateral triangle because the C–O double bond is different from the two C–H bonds, but both planar and triangular describe the appropriate approximate shape of this molecule. What are the three […]
